No channel group in Libreelec but Ok under Windows

Sorry if my english is Bad.

Hello to all of you, I allow myself to contact you because I am confronted with a concern that I do not understand.

I have an IPTV subscription in the form of m3u list. I sorted, renamed, lifted this list, created group-title etc ....

When I do this kind of thing or modification of skin for example I test on my Kodi Pc and then I send to my Kodi HTPC which is under Libreelec.

On Kodi under windows in the TV showing the menu on the left I can choose my channel groups no problem but under libreelec the channel groups menu is empty I do not understand.

I join a screen of group channel on my Windows Kodi

did you tried to reset/clear the pvr db (at the pvr settings) ?

it should and it does behave exactly the same as at windows

Yes i did it, also hard reset on my Libreelec settings and make a new start but steel the same.
