Blue screen background

[DrParker]

Hi everyone.  When I start my videos my virtual background is on a blue background despite every thing being on none /off.  No avatars are on etc, no green screen on.  I am able to shift through other virtual backgrounds.  But I cant get it to have nothing on there yet.  Can someone please help me make it so I do not have a background on my screen.  I am not certain if I hit something in the past, but I am uncertain how to take it off now.   Please help.
