Change ebook Vendor when only option is Adobe ID

[atacon]

I am unable to authorize to a new computer because the ebook Vendor option window will not open to allow me to select the correct vendor (BooksAMillion). Thus Adobe ID stays in space of ebook Vendor.

On the Authorization window where you have to put in 1) ebook Vendor, 2) Adobe ID, and 3) Password. The #1 ebook Vendor option should open where you can scroll down and select stores where bought ebook from.

And the Scroll down option was not open?

Same problem on Windows 10.  eBook Vendor is greyed out and there is no pull-down to select another (Overdrive in my case).  Any help with this?
