I Zimbra opensource 8.0.7 in production.
I have a problem adding color labels on my calendar.
I have created two labels "Made" (green) and "Descent" (red) to mark my calendar items.
When I tag an item with any of the two labels, label appears a multicolored and standard item remains in color.
See the attachment to understand what I say.

Item "REUNION UPNA" is supposedly green labeling
