Virtual background wont return to default None/ Blurred

I added a color to my virtual background somehow. I cant find that option to disable it anymore and the default None/ Blurred retains the  pink color accidentally selected. How can I return it to default None Background- BTW- I do have it set to None already and its staying pink. Cant get a live person to help. Any one else had this and corrected it? Please email me *********** if able.
