The favorites do not work, however I think I found the solution.
AC25 applies some building material to its default CW door, window etc. I do not have these building materials or have renamed them in my streamed down template. In my case, they come through as "MISSING" and render the favorites unusable.
I went to the out-of-the-box (OTB) template for AC25 and grabbed a curtain wall there and placed these materials back in my file. Favorites seem to work now.
