Problem with a deleted solution.

Hi, I have this problem.

I created a solution in ByD Studio, I made some BOs and their screens, then I deleted all the solution, all of this in the development tenant, now I'm trying to request a test tenant but it can not be released because there are some problems with the developments, but the solution is already deleted, so, there's something else that I have to do to fix this?

Another thing is that, when I try to modify the right access for an user, I mean, the work centers ans views that this user can access, it shows me a trouble where says that I need to delete some screens (the screes who belong to the BOs in the solution already deleted).

I hope you can help me.

Best regards.
