Mass edit normalize and loudness functions

while using the mass edit because of adding multiple tracks in the database app I noticed the following points;
After using normalize, the popup says it’s done, but the process bar keeps flashing.
When pressing the loudness button (also in massedit), you will receive the message 'Already started".

I was using it for editing 2 items in the darkskin mode when trying.

Update snapshot 5008;
Loudness is working well (solved)
The blinking bar after normalizing is still visible.
