Bug: DatePicker year issue since 1.6

Good day

Since the 1.6 update, the Birthday profile field on my user profiles has become a nightmare.

Regardless of what year you pick, the option displayed as the selection does not update – It saves what you have chosen into the field itself, but the datepicker display is no longer showing what year the user has selected(If I pick 1991, the year on the drop down after clicking 1991 is 1947. If my year is 1991 and I click on the date field, it shows 1966 in the drop down on the datepicker.

Example:

This has only started occurring since the 1.6 update and as this is a common location javascript file native to wordpress, please advise what in Arcane may be overriding or conflicting with this – According to changelog the change regarding date picker was made to the registration page template and not to buddypress profile structures. We have reverted the below custom changes we made to datepicker.min.js in /wp-includes/js/jquery/ui

yearRange:"c:-10:c+10"
to
yearRange:"-100:+100"

The changes were originally to allow users older than 20 to be able to choose a birthdate. Reverted this to see if that was conflicting with updated theme, no resolution.

I will upgrade the support user back to admin for debugging as soon as the team page issue is replicated by yourself.

Thanks in Advance
