SSL user bookmarks desynchronize FMG

Hello,

I'm facing a problem with SSL VPN users in web mode: when they create personal bookmarks, the FG is desynchronized from FMG. When I try to install from FMG, the installation fails. The installation report shows me the following message, but does not help me find what to do:

---> generating verification report (vdom root: vpn ssl web user-bookmark "user-x#" bookmarks "user x":url) remote original: to be installed: "10.1.5.80" <--- done generating verification report install failed

Any ideas?

Thanks
