Issue Summary

Labels containing "+" character do not filter correctly at workspace and board level.

Steps to Reproduce

1)Create a label with a "+" character (e.g., "TEST+PRIORITY").

2)Apply this label to different cards on different boards.

3)Try to filter the cards on the board with this label.

4)Create a saved Workspace view with this label and try to filter the cards — it returns a "no card found" error.

Expected Results

Filtering should correctly return all cards with that label regardless of the "+" character.

Actual Results

Filtering fails for labels with "+" at both workspace and board level

Workaround

Avoid using "+" in label names and use alternatives like "TESTPRIORITY"
