Weird trapezoid-type shape shows when trying to enter text into Table cell (Publisher)

[Quesadilla]

I have designed a calendar and all we well until I started to enter the dates for one of the months (just numerals, as in 1, 2, 3, etc.,) Black shapes appear, of varying types, with a kind of white circle where the numeral goes. I can't figure it out. Any ideas? Thanks! Here's an example:

That looks like a massive stroke has been applied to something, the cell borders perhaps?

Hi Quesadilla,
Welcome to the forums

Looking at the screenshot I would say Old Bruce has likely hit the nail on the head! If you have any issues removing the stroke please let us know.

Thanks

Thank you both and apologies for being tardy in responding. I haven't had a chance get back to the project until this morning. I would welcome help in fixing the situation because I'm flummoxed. (BTW, I guess the words "massive stroke" are never a good thing!). I can't find where settings for the tables—how I built the calendar months—are different from one to another. Ex: as I entered the numerals for the days inside the table cells for Jan, Feb, Mar, etc., all was fine but starting in April the crazy started. I've built each month's pages using a master so, again, how things got changed I don't understand. I'm all for learning to fish, but I'd appreciate if someone could toss me a fish for now. Thanks again!

Hey! I caught a fish!! You were right, although I was looking in all the wrong places to fix the problem. It was a ginormous stroke (set to 12 pts instead of the appropriate 0!) I copied and pasted some entries from the correct months' grids and pasted them in the bad result grids. That worked fine, but a work around instead of actually correcting, and learning about, the problem. So I deleted the pasted number in one cell, typed it in again and got the same issue. Reverted back to the pasted text. Out of the corner of my eye I notice a change on the text setting in the pop-out box. Control-Z, saw the actual change. I had been looking in the table formatting box instead of the text formatting area. Thank you, thank you, thank you!
