The zoom feature may have been at fault for a while, but everything is back to normal now. Thanks for all of your input. I appreciate your willingness to help!!!

Thanks for the question, Walt.
It is now easier to copy the number without the pop-up telephone number interfering. 
The other good news is that even if the white letter in front of the black numbers is copied, the website, findagrave, recognizes only the black numbers. 
That works even with shorter numbers of which some had the same problem.
It now works to find the memorial of the deceased person. Hurray!
For now this seems to be the best solution short of placing hyperlinks.
I will keep exploring alternatives.
Later edit: I broke down and started using hyperlinks. I just discovered that color-coding for generations can be used with them. Well, I keep learning and enjoy the fun of problem solving and discovering what I didn't know. This program is more powerful than the previous one I was using.

h_d, I just downloaded Adobe Acrobat and it does work for me, too.
I will suggest that option for those who receive my pdf.
I couldn't find a way to turn off the telephone number pop-up in Preview either.
I have been working all day on this problem that has been puzzling me.
h_d, you have been very helpful.

In macOS Preview you can ctrl-click on the number and then choose Copy from the contextual menu:

I have tried Acrobat Reader for Apple Mac with my test pdf and it doesn't display a phone number popup. 

I have no idea what alternatives might exist on Mac. Perhaps a Mac user can suggest one that isn't this helpful.

Thanks, Brian. I found it under View ... Studio ... Transform.  I so appreciate your help. Thank you.  I will update to v2 soon.

Thank you all for responding to my inquiry. I finally understand. I had not noticed that the toolbar changed at times depending upon the selected item.  Now that I have been doing multiple grouping of items, that must have thrown me off. Thanks for the input from all of you. I am slowly learning more of the complexities of this great program. I LOVE IT! Today I used hyperlinks for the first time in genealogy work I am doing for a friend. I wish this program had been around ten years ago. I have produced around 800 pages of genealogy using a very simple desktop publishing program, Ready,Set,Go with very few of the capabilities of Affinity Publisher.  Again ... thank you!

I saw a pencil in one of the tutorial videos and wondered. 
Under "Stroke" one can vary line size, etc., but no way to get a line except make a very narrow rectangle or around shapes. 
My old desktop publishing program had texture to apply to lines with a line tool and a pencil.  I hope those can be integrated into Publisher.

A_B_C, thank you for checking this out for me. I appreciate your offer and the time you expended to find an answer. I will certainly keep OCR in mind for future use. Thank you for your willingness to help one who is a novice at much of this.

I also have the program PDF Expert which is an editing program. I can load the document into the program, but it immediately switches to symbols when I insert the cursor into a section. 
Fortunately, so far I have found only this one PDF of 8 pages that has this problem out of about 770 genealogy pages. I'm keeping my fingers crossed.
