Due Date field keeps reappearing in the backlog view settings

[Callum Davey]

Hi - We have a field in our company project called Due Date.  I have this field disabled from the backlog view settings because I dont use it, but since the major UI update rolled out a couple of weeks back, when I disable this field (screenshot1), and then refresh the page, it comes back re-enabled (screenshot 2).  This does not happen with other disabled fields.

any ideas?
