New Officers not populating - 2580012 - Speak Up 900!

I have tried to change the officers in our administration toolbar, but they are not taking. I have also uploaded a more current members list, but don't know what to do when the information (i.e. phone number or email) has changed. It seems to be giving me trouble. Your help is greatly appreciated.

You change officers by scrolling down to the bottom of membership management and using the Assign Ofices, guests and former members selected, then choose their status.

To change an email or phone number, use member management, but only make 1 change per member at a time, saving between each change.
