There are a few issues of the PE and I think there a few min. radius too.
If you need a Berk to make tight 0-27 turns all day; you need a Berk Jr like a 2755.
I think they did a PE Jr, but not positive.
The bigger ones need 0-36 to be truly reliable imo.
Roller width/position / tape bit is also a good possibility though.
It isn't 100% compatibly just by brand; some things need "convincing" 😜
