Gnome Menu hidden behind applications - multiple monitors

Hello Guys!

I’ve just switched from KDE to Gnome and facing this issue.
I have to monitors, one inbuilt in my laptop and external LG. Default one is my laptop’s screen, however when I open the app menu, everything is displayed on the external one. I don’t know how to change it. Also, when some applications are displayed on the external monitor, when I open the menu, all the applications and workspace sidebar is hidden behind the applications miniatures (photo attached).

Can somebody help me?
