[Error] Having an issue with evolution and Pokedex entries

[Loginator1113]

So I'm at an early point in my fangame and I just evolved my Charmander, only to suddenly get an error message right before it goes to the Pokedex entry and the Charmeleon duplicates to be both on the evolution screen and where it would be for the Pokedex entry. In fact, my previous caught Pokemon didn't get Pokedex entries either. But I can't figure out this error message and what could possibly be causing these issues.

Spoiler: Error

[Pokémon Essentials version 21.1]
[v21.1 Hotfixes 1.0.9]

Exception: NoMethodError
Message: undefined method >' for nil:NilClass Backtrace: [Generation 9 Pack] Footprint Replcement.rb:14:in drawPageInfo'

I couldn't tell where I had to go to fix the issue. I tried removing a whole folder for "Footprint Replcement" in the Generation 9 Pack Plugin yet somehow it didn't work and still got the same error. I could use some help thanks.
