I'm dumb, I forgot to mention that I need help to fix this bug ¬¬

hello what is the problem? can anyone help?
I have reinstalled and the problem persists. dark ritual is also causing the same problem, apparently is happening with any effect that adds mana tokens. please if someone could help me I would greatly appreciate

Is this for a mod you're making yourself?

solved thx is a deck, I needed a mod.
