I tried to change the google merchat configuration but it does not allow me to

Hello,

I tried to chage the information in the google merchant configuration but it does not allow me to do it. I authorized a google accopunt that I don’t want anymore but when I click on the reset button It says that is still authorized by the same account. I does not allow me to chage that account no matter what I do in that page, even if a place a random key in all the fileds It stills says that I am authorized by the same google account. I would really apreiciate your help telling me how to reset that authorization in order to place other account.

I share a link of a google drive folder where are some photos to help you understand what the problem is. GOOGLE FOLDER: Here
