Remaining monster count doesn't update

I've had to either re-enter the map, change areas (as in trophical island cave etc. but doesn't always trigger) or using the "/remaining" command to trigger the update on monster count all this league (Necropolis).

Thought that was a common issue but figured not. Anything I should do about it?

I was also seeing this today.

And had a few maps where it still said more than 50 remaining even after clearing the map and running around to all the corners to make sure it was clear. Going to hideout and back and /remaining didn't update it then either.
