Fabfilter Pro Q3 insert raises track volume

Inserting an instance of Fabfilter Pro Q3 as an insert on a track raises the volume ( audible, and visible on the meters by at least 6dB) of that track without doing any changes to the plug-in!

I’m on latest version of Windows 10, HP Z820.

Do you have Auto Gain enabled ? Could cause something like that!
I use it all the time - no issues over here

I have a freshly installed new PC now, no more issues…
It wasn’t an auto gain issue, but thx for your reply!
