[BUG] Level is marked as Used when all belonging elements have been deleted

Here's a bug I've found in MicroStation v10.16.1.319:

I removed all elements from a given level, called "NOELMS". The "Level Display" and "Level Manager" still mark it as Used, with the black dot and 7 element in it. However there isn't really any element.

Opening "Level Properties" from "Level Manager" actually shows that there's no element in the Count section.

Closing MicroStation and opening it again solved the issue, now it's displayed as not used.
