For anyone who hasn't checked the threads: it seems the Terra and Ven files can mis-read the final episode in... some manner. This impacts the difficulty level of Radiant Garden: either the glitch causes the level to rise from 6 to 9/10, or the glitch causes the files to stay at 6 when they're supposed to go up!
But like MSullivan summarized, no one knows whether the game is supposed to upgrade their levels or leave them at 6, so it's become a huge tangle. If you don't know which is the glitch, you can't know which players actually have the glitch, so can't work out what they did to get it!
I decided to just start Ven's file over completely. I figure it shouldn't take me much longer than 6-7 hours to speedrun it on Standard. Now I'll just know to save a separate Non-Clear-Ven file at KG before fighting Ven's final bosses. That way I can continue to test if the glitch (or anti glitch?) happens again without having to replay the game.
I'd urge anyone who hasn't delved into BBS yet to save separate files prior to the final bosses aside from your clear files so you can figure out the glitch if it happens to you as well.
After some more extensive research, it seems that after you complete Ven's game, you
cannot even load his clear file prior to completing the Final Episode with Aqua, or the levels will remain low. Someone recommended that I just beat the final bosses on Ven's clear file to see if it reset, but I think the game recognizes the clear files and non-clear files differently.
