Fixed position when scrolling doesn't apply to daugther components (and it's impossible to turn it on at daughter instance)

After testing my prototype with detached instances I began polishing it up using daughters of main components I have created, just to make my life easier when adjusting the UI on the go.

I noticed a component I designed wasn’t behaving as intended (and as previously tested). I corrected the settings, including the “fix position when scrolling” setting, making it exactly equal as the version tested, but again, it failed. I then realised this particular setting wasn’t being applied to the daughter instance!

I tried everything I could, but enabling it at the daughter instance seems to be impossible. Can anyone help me out?

It is not possible, this option is not supported in components. You can vote for this suggestion: Request: Fix-position for components
