Hi Olav!
Thank you for the report and feedback. Do you have several rules that hides the same field/dropdown?

The disable option is a good idea. Will add this.

It would be a very big limitation if that is the case. Testing a bit further, it might even look like it is applying the rules somewhat randomly for fields that is mentioned in multiple rules.
