How to Force EPG Update

Hello,
Updated to Release 11035 Server and TV Source.
Need to Restart my Synology DS412+ with DSM 5.1-5022 Update 1,
otherwise DVBLink shows to me not device
After reboot the EPG Data was empty, need to rescan all channels to get valid Data.
2 days later now the system shows on a few channels unknown Data.
Please add a Button on "DVBLink Client - TV guide" view for easy epg rescan all
channels or selected channels to immediately update the missing data.
i have at this time the view "unknown" at German Channel "Das Erste" and don´t know how to
delete and force to update the missing/corrupt data for the system!
thank yo
Ralf
