Form Customization Tab Rang not saving or random number after editing. Bug?

When editing a "Form Customization" set and modifying a "Region Rank" from the column after saving everything looks fine.
After reloading the page or re-opening the set the changed values are back to default or even random numbers.

Is this a bug?
Can anyone confirm the same problem?
Is there a workaround?

This guy has the same problem, and his post is from 2013...

I think it's a bug, probably related to this -https://github.com/modxcms/revolution/issues/5537
Unfortunately, form customization is a mess right now.

I've tried this in May 2018 and the order is somewhat changed consistently, but is not sequential.

For example:

Image - 1
Layout - 2
Thumbnail - 3
Description - 4
Location - 5

I'll get a layout like:

Image
Thumbnail
Location
Description
Layout

Any attempts to change the Region rank for each variable results in no changes.

Thanks. That did the trick.
