Hi, it seems like the text in the first PDF is unreadable. The trifold also has an unreadable page, but at least it's readable in the photo gallery.
Thank you for bringing this to my attention. I will look into it, but please try to redownload the files as something may have been corrupted during download.
I figured out the problem. It only looks corrupted on the Readera app, when I open a preview in my browser it looks normal.
This is what it looks like in Readera.
