GA4 Custom dimension not set


I’ trying to import a property from Googlle Analytics 4 (GA4), and I think the custom dimensions I have defined on GA4 are not prroperly imported, all my custom dimensios have event scope (action scope), and after exporting the site aparently well, when I see the Behaviour/custom dimension section, I don’t se the dimension splited by name, I can see that the dimensios we imported, but the label of the dimension says not_set_in_google_analytics_4.
Here the image:

I was expecting for example for the cinemaName custom dimension, the count of actions for each cinema name

I’m trying to debug but I don’t find the issue, can someone help on this please?
