Random Sentences Capitalized when Exporting as a PDF

Every time I try to export my file as a PDF, random sentences are capitalized acorss multiple pages, and on one page one of the photo crops is different. Obviously this is not how it looks on the adobe express site. I've tried downloading as PNG and then converting to PDF, but when I do that, random images / assets are blurry. It is a large document, 67 pages. 

I'm using the fonts Lato and Lora. 

I've tried exporting it in every way imaginable and nothing changes. I've tried deleting the assets that are showing up strangely and re-entering them but it still happens. Always on the same pages every export despitre trying all of these things. 

My deadline to submit this work is 11:59 pm tomorrow so I am looking for help as soon as possible!
