Tvheadend

This has been bothering me for a while, when I launch TVHGuide (v1.6.7 from Yalp Store) I will see old EPG for most of the channels
so for example BBC One HD is now Sun 10:45 showing as having on:
BBC News 00:20 - 06:00
next
Breakfast 06:00 - 08:35

When I click to Play the channel and then go back to EPG, it will update all the EPG for channels from that multiplex ...

TVHClient v 1.9.12 for Android on the same device and TvhClient v3.3.2 (867) for iPad work great and show EPG correctly from the same TVHeadEnd (HTS Tvheadend 4.2.7-34~g036b9cbab)....
