eReader Prestigio: Wrong Titles from Web

Anyone using the eReader Prestigio app for Android? There are a lot of things I like about it, but I've noticed it consistently displays the wrong title when downloading epubs from the web.

Prestigio accurately parses/displays personally epubs that are personally owned, loaded from Calibre Companion/Calibre Cloud, and downloaded to a watched folder.

When downloading an epub from an online site, specifically Archive of Our Own, the downloaded book shows up with a different title. Additionally, the percentage read amount is past 25% and the book opens to a random page in the middle of the story. Strangely the book title shown is always something that has been downloaded before but has since been deleted (both from device storage and from browser download history).

I know the new book has downloaded correctly because (along with working fine for the million other apps I've tried) when viewing book info, the path directory lists the correct book title.

This is happening with downloads from both Firefox and Dolphin. I've never encountered this before and the issue seems specific to Prestigio. Anyone else encountering this and have ideas on how to fix it? It's much more irritating and confusing than you might expect. :)
