Level 4 Slot Total Permanently +2

I have a Warlock character who's level 8, so they have 2 pact magic spell slots at level 4 at the moment. Somehow something happened with the "lvl4_slots_total" attribute where it's consistently correcting to be 2 more than I want it to be. When I update "lvl4_slots_mod" to 0, the total slots updates to 2. When I update the mod to 2, the total slots automatically updates to 4. Considering I'll need to change it to 0 once I reach level nine AND I want to eventually multiclass, I was hoping someone might know what might be happening here and how to fix it? I'm using the 5e by Roll20 sheet. Thank you!

I just realized that I might be dumb. I started playing this character a couple years ago and our group took a break while most of us were in our senior year of college, so when I first made this character, the Warlock slots were always 0 and you had to use the mod to fix it. Was the Warlock class updated recently so you'd actually have the spell slots you had? If so I am a BIG dumb and I apologize.
