[Preface(I can't code, this was trial and error, these are assumptions and a "working" solution)]
The problem lies with Lust Epidemic and Treasure of Nadia, as they are capable of sharing save data with each other and NLT decided to implement a system where players are unable to edit save data of a game they are not currently playing, apparently forgetting to restrict this "safety" feature to just their two games. The code sees that we aren't playing either game and defaults to locking our save data. Resulting in these past months of frustration
This "fix" worked for me, rip if it doesn't for you (I wiped my LE save)
1. Open the game whose data you want to keep
2. Open the other game without closing out your keeper game
3. Reload the the page for your keeper game and load a save
4. In your keeper game, save over every slot that contains saves for the other game
Check 1. Reload the the page for the other game, if the continue option is grayed out, that's good
Check 2. Open a RPGM game of your choice, load a save and then save into a new slot. Reload to see if the new save stuck, if it did you're good to go
Edit: The fix only works if you already have save data for a game
