CrossEPG now, next, later issues on Zgemma 2s

[blacky1973]

Hi my Zgemma 2s is having issues with the EPG, whatever is on TV now is also showing as being on next and later,
eg... If the news is on from 1:00-1:30 it's also showing as being on next 1:30-2:00 then again later 2:00-2:30,
how do I resolve this?
thanks.
