ApexSQL Complete confused, shows unwanted dialogs when running two instances of SSMS despite each instance working with a different database catalog instance

Hi, has anyone come across this?

ApexSQL Complete appears to be confused. It shows unwanted dialogs when I’m running two instances of SSMS despite each instance working with a different database catalog instance. It thinks I might be interested in changes I’ve made in the other instance.

SSMS is the latest version v18.6.
