I asked you what returns because we need to know what we have (post object or post ID) to do the relations between the addon and the current post.
So the add_ons_suites is a relationship which contains a single value of the post ID or multiple values of posts IDs?
And another question, the add_ons_suites is a field from the cpt addon or the current post?
This questions will help me to give you a better resolution
