Issue with Slider Property Editor UI mandatory when initially not set

There seems to be an issue with the Slider Property Editor UI type in the CMS.
I’ve created a slider type for managing paddings and margins on a block grid module.

When a module is initially added, the default value is 0.
If the user then saves and publishes, it flags with a red ! and you have to go in a set it a value, save and publish then set back to 0 / re-adjust them.

I’ve checked the editor type and its not set to mandatory so its like the initial value isn’t being set on load?

Am I going mad or are other people having this issue?

Hi Sam, this is a known issue that is fixed in latest version. So update and the issue should be gone.

Hi @nielslyngsoe Thank you for replying.
I’d done the update before this post but just for sanity I’ve checked the page data again and it seems to still be an issue:

I’ve used a simpler layout where the values are not set for just the sliders.

Side bug, when the error flag is flagged, I also have to refresh the page to edit the data again as the “update” button locks.

Currently got the 15.3.1 update installed:

These are the values for the slider:

And the field:

Many thanks,
