MForms radio buttons (and check boxes) rendering random widths (no replies)

Hello,

I am facing a problem with a UI that randomly changes the component width on subsequent dialog displays.

Sequence of images here:

Correct rendering:

Wrong ones:

https://pasteboard.co/HUkISMC.png
https://pasteboard.co/HUkJ2HS.png
https://pasteboard.co/HUkJcHy.png

Top image is as it should render. Notice the random left aligns with all other images.

What's wrong here?

Here's the code that creates the UI:


from mforms import *
from abc import ABCMeta

@ModuleInfo.plugin(...)
@ModuleInfo.export(grt.INT, grt.classes.db_Catalog)
def export_jpa_annotated_classes(catalog):

do_export = Builder.ask_for_options()


class Builder:

__metaclass__ = ABCMeta

Maybe it's something for the WB team to look at, as it is absolutely not understandable why this is happening...

I'd very much appreciate if you could have a look at this.

Thanks and happy new year.
