Issue Summary

Labels on Trello cards are disappearing when specific Butler automation rules are triggered. It's also happening when moving cards manually. But it's an intermittent problem.

Steps to Reproduce

Automation:

1. Set up a Butler rule to add a specific label to a card when the card with a designated description is added to a particular list. Then, move the card to the top of another list on a different board.
2. Trigger the Butler rule by adding a card with the matching description to the specified list.
3. Labels are not copied while moving the card

Manually:

1. Add some labels to a card.
2. Manually move the card to another board by going to the card menu > move the card
3. Some labels are not copied while moving the card (if moving the card back to the previous board, the labels will show up again).

Expected Results

The card should retain the added label as it is moved to the new list on the designated board.

Actual Results

The label disappears from the card after the Butler rule is executed or manually moving the card.

Workaround

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