UPD: please see my last comments for the updated investigation.
I have a problem in alpha/beta with macros that is hard to track.

There is a group of macros defined on the template level: {$PORT1_DESC} – {$PORT48_DESC}

Also some could be redefined on the host level.

There is a bunch of active events in the system. And these Macros used in names could be relaced or not. It seems that sometimes they are not replaced with the value

For instanse, in System Status on the Dashboard, the following events have problems with MACROS:

On the other hand, SAME events have no problems with MACROS if another view is used, for example in 'Status of triggers':

So it looks fine for the most of the time, but there are around 5 triggers in the system which macros in names doesn't open at some views.
