          > > I had the same issue just now. In my case, the problem is that I did not clear out the existing feature extracted before I add in the mask. Removing the database and project.ini file in the project folder before creating a new project solves the issue. I hope that this could be helpful.

I started it from scratch, and I still have the same problem.

did you solve the problem. I seem to encounter the same issue that mask are not working
