[5E OGL] Can't add bonus spell slots to character sheets?!?

I'm still in the process of re-writing 5E into something actually fun to play... It's quite allot more work than one might think -.- Yesterday I came across something I can only see as a bug. I mean, after over 10 years if it's still not possible to add bonus spell slots to spellcasters in 5E, a whole bunch of people deserve to be fired ASAP lmao... *FacePalm* So there's buttons to modify the remaining number of spell slots a character has left, but that's not what I need. Ideally I'd need to be able to add a number of spell slots for a number of spell levels. Those slots are meant to be on top of the slots given to the character from all his/her various classes. So any idea how to un-bug/fix the sheet to allow it? Or has it been omitted for over 10 years?!?

It is working correctly for me, are you changing the "Spell Slot Modifiers" on the settings sub-page for the character sheet?  Could you screenshot that page?

Hot dam, I never even saw that in the options... Guess who needs a brain transplant? >.<

Thanks again Gauss *ThumbsUP*
