[Issue]: Control: type mismatch when saving parameters causes an exception

[lbeltrame]

Issue Description

When doing something similar as #3067, I instantly hit an exception when I hit "Generate":

03:59:17-838769 ERROR    Control exception: 'float' object is not iterable      
03:59:17-839800 ERROR    Control: TypeError

TypeError: 'float' object is not iterable

The only difference from the workflow of the previous issue is that I loaded a pre-existing image (made before the latest parameter changes).
