Independent barline pickle

Getting myself in a pickle with independent barlines. I have independent metres already. But when I alt-enter a selected barline, it undoes the independent metres. I’m doing something obviously stupid…

(why the heck does spellcheck change barline to carline every single time… wth is a carline??)

Take your pick from a type of thistle, part of the structure of a ship, or a witch (though I thought the witch was a carlin, not a carline).

In the UK, it’s also the name of a motoring finance and loans company.

It’s only the this forum that predicts it… not exactly a frequently used term…

In other news…a restart of Dorico and it now behaves nicely, dashing my barlines.
