I was a bit frustrated as well, but I finally figured this out.
I had to move a new project to BS5, so that was causing me problems with older TA instance I already created on my page…
I took screen shots of my TAP settings for the Bric I was trying to get working.
What I did: I went into page settings and deleted the Tab Anything that was there under extensions.
Then I went back into my page and added the new Bric for TA Pro next to the content I already had created.
I had to rebuild the menu some, but I eventually got it all working the way I wanted it.
Not really intuitive, but with some tips from Whittfield I was able to get this done and I AM NO PROGRAMMER.
Hopefully, this will help…
