Hi Chris,
Thank you for sharing the issue!
At first, the complex profile shouldn't be empty, or else you won't be able to save it (for some reason, a profile can be empty if you close the Profile Manager right after it is created). I came across many cases where somehow the profile does not include any fill, or the fill was corrupted, which leads to a symptom similar to a far from origin project. In those cases, I can only delete elements one by one, in order to pinpoint what is exactly causing it. It takes a lot of time, but this is the only way to solve it!
This is a limitation of within the code, I believe. I am very sorry about the inconvenience, but I'm glad that the problem is solved for you!
I wish you a great week ahead!
Best regards,
Minh
