FRANZ says I don’t have spells prepared

I have spells prepared. I go to cast the spell. Franz says “but you realize you do not have that spell prepared or available in your current repertoire“ whenever I haven’t cast that spell in awhile.

It happens so much I had Franz make an instruction stating:

“Spell Casting Mechanics for Player: When the player character Giller states that they cast a spell that they have prepared and have an available spell slot, the spell must succeed. The DM may not declare the spell failed or indicate it is not in the player's repertoire. The spell always works as described by the player, unless a narrative reason that was already established before the casting prevents it. This rule overrides any previous guidance about possible spell failure.”

And it’s still happening.

This is frustrating because I mostly pay for and use credits for my messages, preferring GML-4.7 and whenever this error happens I waste at least 2-3 messages correcting FRANZ, tripling the cost and having to deal with the issue.
