For what it's worth, we've already done a significant UX update for the right pane for the next Forms release. Instead of just showing rules where the selected field is the target, we show rules where the selected field is involved at all. We also included a toggle to show all field rules in case you change a condition to make the rule disappear. I think this issue you describe is because we assumed the target field will be Company (based on your selection) so you wouldn't set the condition to be Company as well.
With the UX updates, this will not be a problem anymore, it is already fixed in dev. We are looking to gather the feedback and fixes for the layout designer since the initial Forms 11 release and roll them up into a Forms 11 update at the end of April or early May.
