Can't delete an old Vmail Relay notification

Hi everyone. My RELAY notification has been lit up red for about 3 months now for a station with Vmails for me to collect. The DELETE button in the notification window has no effect. On the bright side, the "Last heard" column now reports the station with my message(s) CQ'd 49 hours ago, so there may still be hope that I can connect eventually.

Does anyone else have a problem with deleting old relay notifications?
