Issue Summary

There is an issue with Trello automation rules where not all labels are being removed from a card when an automation rule is triggered. Specifically, the automation intended to remove all labels and add a specific label based on the list the card is moved into is not functioning as expected when a large number of labels are present.

Steps to Reproduce

1. Set up an automation rule on a Trello board to remove all labels from a card and add a specific label when a card is moved into a designated list.
2. Move a card with multiple labels into the target list.
3. Not all labels are getting removed.

Expected Results

All existing labels on the card should be removed, and the designated label alone should be added to the card. 

Actual Results

Not all labels are removed from the card when it is moved into the target list, despite the automation rule being triggered. 

Workaround

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