I added notifications for the Slack Power Up and now receive 4 notifications in the same Slack channel for the same change/action made on the Trello board.

When I attempt to edit the Slack Power Up in Trello, it only ever says 'Loading alerts for board', so I can't tell if there are multiple notifications set here causing the issue.
I've also checked via another browser and asked a colleague to check too - all have the same loading message. The latest attempt to wait it out has been around 15minutes and it still says 'loading'.
Is this where I'd solve the multiple notification issue? And if so, how do I resolve the loading issue?
