Having difficulty reproducing it here. Anyone having similar issues on a released edition of Gitlab?

Other Notes

You can see in the Activity Pane that sometimes the change saves and everything will change back upon refreshing the page or re-saving the issue.

This seems to occur for checkboxes that are after an empty checkbox, as shown in the example above.
