Hey everyone,
First of all, thanks for any feedback. So, this is my problem:
I have created custom issue types called "request" and a related sub task called "profile". Both of them are assigned to the same project and have their own workflows and screens.
However, whenever I want to create a "profile" it gives me this message: 
Of course, I tried again several times. In other projects, I can create subtasks as usual without any problem.
Does anyone know what I could do?
Thanks
BR
Michael
