Many thanks for your post and apologies for the inconvenience caused.

Let us know if this happens for all the alerts on that server? Does the behaviour changes for the other SQL Server added (if any)?

Have you tried restarting the Alert Repository service? Kindly let me know if this makes any difference.

Of the 3 alert categories, this is the only one that causes the problem.

Alert Service restarted. UI bombs.
