bottedumal Hi, we fixed some sort by name issues in v1.1.1(606). Please try using the new version to see if the problem is solved. You can click Global Settings and turn on Show FPS to check the version number.
If you stream videos from computer to Quest 1 via SMB file sharing, the "some files not showing" issue should also be fixed in v1.1.1(606). Please have a try and let us know if you have any other problems.
