Elementor not retrieving taxonomy data

Hi,
I created a post type and a taxonomy to be attached to that post type at Custom Post Type UI and then added a taxonomy field at ACF, choosing the taxonomy previously created to be displayed. That worked fine at the edit screen, but when I go to Elementor Pro it doesn’t seems to find this data as taxonomy (it finds the category itself, but says that there are no posts with that category). If I put the category directly at edit screen (without using ACF), Elementor finds the data correctly.
What am I missing for the taxonomy to work with ACF?
Tks,
