PDFs in proofing tool look strange now

Hello, the PDFs in my proofing tool column look strange today. The fonts are messed up and the pdfs are now barely legible. I see that the proofing tool possibly had an update last night, since we can now use squares and arrows (which is a totally awesome update that will be very helpful!). Is there a way to fix the pdfs so they look normal again?

Attached are screenshots of how it should look (bottom) compared to what I now see (top) in smartsheet.
