linux newbie here.
I recently installed ubuntu 18.04 over windows 10 yesterday, and was trying to make the taskbar somewhat like the windows one. Along the journey I somehow ended up with 2 taskbars and am confused at how I would get rid of it. I have the default one (which I want to keep), and this. I am wondering what extension that gnome has would produce such a taskbar. For some extra information, here is the gnome tweaks extension page for me.
Edit for Clarification:
I am wondering what extension produces this, and how to disable it. I don't really know how to clarify this much more than I already have.
Thanks
