datetime field potential bug!

I believe there may be a bug on “datetime” field
I’m using Joomla! 3.5.1 & Community Builder 2.0.14

What I want to do is set the date to display month, day, and 2016 year only, and time to be hour/minute, without seconds

in Parameters > Display > Custom
when changing Custom Date Format or Custom Time Format and save, it Successfully saved Field but changes does not apply in the user’s profile.
Example:
Date y-m-d change to m-d-y changes does not apply in the user profile.
Time H:i:s change to H:i or H:M changes does not apply in the user profile.

In Parameters > Validation
I want to display the 2016 year only, when it set:
Minimum Year 2016
Maximum Year 2016
OR
Minimum Year +0
Maximum Year +0

It display 2016 and 2017 at the user profile (adding 2017)

Displaying M-D-Y H-M-S doesn’t change at the user end no matter what changes in the field setting

Thank you

I am unable to confirm. Note format does not affect profile edit at this time.

Yup, we add an extra year if the min and max are the same year. It's not possible to have only 2016 selectable.
