I have found a temp solution.
Convert the rar and 7z files to zip.
Option 1: rename a .rar file to .zip and the app will read it, doesnt work with 7z files.
Option 2: Use Winrar's Convert Tool under Tools > Convert Archive to bulk change files from RAR and 7z to ZIP.
The downside to this is a file size increase, testing with 8x7zip files it went from 1.30GB to 1.48GB. Probably will convert the 7zip files and extension change the rar files.
Ill try to email the author of the software to see how to fix the issue.
