Issue Summary

User is trying to use the following trigger: "When someone is added to a card assigned to anyone" and the action "remove member @

{username} from the card.", the filter doesn't work as expected and removes the member even though there is no one as a member of the card.

h3. Steps to Reproduce

1- Create the automation - "When someone is added to a card assigned to anyone, remove member @{username}

from the card."
Note: using @{matchedusername} is more accurate.
2 - Add yourself or someone to a card that has no one assigned yet.

Expected Results

It should keep the user who was added as a member of the card, as no one was previously assigned (due to the filter "to a card assigned to anyone").
If the card already has a member, it should remove that member; otherwise, it should keep the user just added.

Actual Results

It removes the user that was just added to the card, even though there was no card member yet.

Workaround

Currently, there is no known workaround for this behavior. A workaround will be added here when available.
