Rhino 7 - CPlane in one viewport change the others

Rhino Rhino for Windows

I have 4 viewports - Top, Front, 24, 011 - the last two are perspectives with named views.
I have a Clipping plane active on the Front viewport.
On the viewport 24, I redefined the CPlane. After that, on the viewport Top the CPlane and the view changed to Left (the name “Top” stayed the same); on the viewport Front, the CPlane the CPlane and the view changed to Bottom (the name “Front” stayed the same).
This has never happened before.
is there a lock between CPlanes and views? Any ideas?

Hello - check Options > ‘Modeling Aids’ page for Universal CPlanes. If that is set, switch to Standard

thanks, Pascal.
that was it. I have no idea how that changed and I did not know that even existed.
When it is set to Universal it links all CPlanes?
Thanks again, N
