I suggest a woodoo approach: close Creator and delete a fitter file 'project_name'.cyfit, and *.cywrk files.
Maybe that will help.
All projects have this issue or only 1 project? If only 1 project, could you share the project so that someone can try to reproduce the issue.
I had same issue and pretty quickly found the solution In you Workspace Explorer switch from Source to Components tab. And there you will see this macro somewhere below of TopDesign. Simply delete it and that is it!
