Since today I have something really weird.
In contacts view, all my contacts have the same color ( but I have assigned different colors to each category )
All my contacts ( in list view) display a red color icon. When I click a contact , I see the original category with the original assigned color. When I go back to list view, many contacts ( not all) display the right icon color ..... till next time in contacts view.
In Calendar list view, and in Memo view I have also some items not displaying the right color. But what is very weird not in the other calendar views where the right colors are always displayed.

I am using Outlook 2010 with Android Lollipop 5.01 and DJO 3.1.3 (651).
I just upgraded from Kitkat to Android 5.01 without wiping everything. This could be the reason?

Any explanation or help please?

Thank you,
