RPi TV channel selection and EPG issue

The TV channel gets stuck on a specific (not selected) channel after some (little) navigation through the TV channels.
And there is no EPG information available (no info about current program, no info in TV guide).
Using the channel up/down option on the remote does work normal.
After a reboot I can select a first channel correctly, but changing the channel in the TV channel explorer results in getting the specific channel again.
On the web-interface of Tvheadend I don’t see issues. e.g Electronic Program Guide shows the details I’m missing in Kodi.
Also if I use my iPhone with Kodi 17.0 as frontend and the same Tvheadend (RPi) as backend it works fine.

I upgraded from 7.0.3 to 8.0.0 to 8.0.1, and suspect Kodi got corrupted somehow during one of these upgrades.
I have not seen others complaining about a similar issue.

Rpi3
(128 GB flash)
LibreElec 8.0.1
PVR backend (add-on): Tvheadend 4.0.9 (HTS Tvheadend 4.0.9 ~ LibreELEC Tvh-addon v.102)
Tunner: 2 x Anysee E30 Combo plus (DVB-C Philips TDA10023) (‘DVB-C #0 ad0’ and ‘DVB-C #0 ad1’ in the logs below)

Currently I have only one tuner connected (DVB-C #0 ad0).
The System log of Tvheadend displays the first correct selection of ‘NPO 1 HD’ after I selected this channel.
But when I selected ‘NPO 2 HD’ at ‘2017-03-31 23:36:13’ it shows ‘MTV’ instead.
Making another selection doesn’t give other system log messages.

Search for PVRManager gives the timestamps I selected a channel. The actual selected channels are ‘NPO 1 HD’, ‘NPO 2 HD’, ‘NPO 3 HD’, but Kodi results in ‘NPO 1 HD’, ‘MTV’, ‘MTV’.
