Um, my capital b's are fusing the letters that are with it with itself. Please help

I have no idea what to do. I’ve tried refreshing the tab and closing the tab, then opening the document again, but it isn’t a permanent fix. It’s a pdf, and it’s on google classroom, so maybe that’s the problem. Anyways, please fix this soon. I need this document.

Apologies for the delay in getting back to you. Is that issue occurring with every PDF you load or just with a specific file. If you could send us an example of a file where that’s happened I’d be in a better position to determine what’s going wrong.
