Barnumber bug??

In the score I want the bar numbers to appear centered below below every bar.
When changing the bar number settings as shown in the pic, both the bar numbers printed in the score AND the small blue on-screen ones moves. Is that right?
As you see on the pic, the blue ones now appear in the middle of a system.

The View bar numbers should really be independent of the positioning chosen for regular bar numbers, yes.

So, am I doing something wrong or is it a bug?

You’re not doing anything wrong.

It’s a bug. I think it’s been there since Dorico 1.0
