Patient: Carbonio 23.9

I have a problems with enabling of COS options in Admin Panel. Some sliders works, but several doesn't. Fe, when I change language or disable contacts, calendars... it is also disabled in webmail account of this COS, but if I disable signatures or "User cane specify forwarding address" it is possible to forward email and signatures are visible in webmail. When I check if it is disabled by CLI, it is really off:

$ carbonio prov getCos zcos | grep -i forw
zimbraFeatureMailForwardingEnabled: FALSE
zimbraFeatureMailForwardingInFiltersEnabled: FALSE
zimbraFeatureMarkMailForwardedAsRead: FALSE
zimbraMailForwardingAddressMaxLength: 4096
