Windows not shown in task bar when moved between virtual desktops

[KuenzelIT]

Hi,

I have a problem with some applications where the window is not shown on the task bar if I move the window from one virtual desktop to another. They reappear if I move the window from one display to the other.

This does not happen for all apps, but for quite a lot like: Thunderbird, Nemo (Linux Mint file explorer), Remmina, LibreOffice

It does not happen with Firefox or PHPStorm.

Do you have any idea whats happening here? Below is my exported config file (now that I look at it, it seems to be connected to my pinned apps)

Thanks!
