Brand Yourself Apparel

I need some help!! I made changes, to a logo, in Affinity using styles but for some reason when I go to export the file the styles are not exporting with it. The exported image, whether .jpeg or .pdf aren't showing the styles that I see in the Affinity file. I've tried a whole bunch of different things but its still not working and I've searched the forum but it doesn't seem like anyone else is having this problem. Any suggestions?
