SW 16.22 (CIQ System sw 7.0 added, CIQ API 5.0.0), but in 2025 February cannot install/set ciq contents

Before downgrading my  Enduro 2 from sw18.16 to sw16.22 I had made some cross check whether I would be able to use the same CIQ contents as with 18.16.

I saw that with sw16.22 CIQ System 7 came and there was no change between 16.22 and 18.16.

So I downgraded, but even if I was happy that not just the downgrade, but also the Restore was perfect for the first time for me, I realized that CIQ Store app denied not just any update of my ciq datafields and watchfaces, but also their settings.

  

I am totally confused. Is there anybody who can explain what else I should have considered? If CIQ 5.0.0 is not good for none of my ciq watchfaces and ciq datafields what else should be checked?
