Can't set Constraints for Generative Design

[aleena_thammasorn]

Hi, I’m working on a Dynamo generative design project, but it seems like I can not set any constraint at all. Whenever I try, it just endlessly generates without any results. Anyone has the same issue, any solutions?
Thank you

Hard to diagnose based on that limited info.  What I see in Screenshot is Generative Design in the process of generating a study for whatever you have circled in red. 

FWIW: Info at this link may provide clues:
