Shape Keys Somehow Linked

Hello! I have a project with shape keys, and I’ve run into an issue where one shape key gets activated every time another shape key is activated. I’ve removed all drivers from this shape key, and I have even tried deleting it - it still activates when other shape keys are activated. Does anyone know a fix for this?

Any chance that this one is relative to another one and not the first (Basis) ?

It says its relative to Basis. Also some more info - this shape key goes off even on shape keys I just add and haven’t edited at all.
