Layout: Syncronize views works sometimes

I try to syncronize all my views for technical drawings but can’t get the “Syncronize Views” working properly in this 4 view Template.

Does anyone know why?

Thank you!

Hi Hannes -

Not from that picture, no.
Perhaps one or more details are locked?

As I said, sometimes it doesn’t work. All objects are unlocked. Nevermind, I work around.Thank you Wim. Have a nice weekend.
