Shared calendar does not remain hidden

[7224jobe]

Hi everybody, some of our users have a common shared calendar. A few of them have hidden that calendar (de-selecting it from calendar list on "calendar" tab in the webmail), but when they re-open or reload Zimbra webmail it appears as selected again and all appointments are visibile.
Is there a way to de select permanently a calendar? We are using Zimbra FOSS 8.8.15 with latest patch.

This is a known issue with no workaround.
