In your iptv.m3u.cache,your tvg-id is empty you have to enter that...and always go to Pvr & Live TV settings in kodi settings and Clear data when you make changes to your webgrab or playlist otherwise the cached playlist will not update the changes into iptv.m3u.cache. Do you know if it is possible?
The problem is that my list is loaded from an URL so I don´t know if I can make changes
