OK, I tried to gather more information. I installed previous versions of Kodi in portable mode, and only enabled the Mediaportal addon. 15.2, with the Confluence Skin is the last version where these PVR indicators appear properly. They do not show in 16.1 with Confluence Skin, 17.0 Beta-1 in Estuary skin, or 17.0 Beta-3, with Estuary or Confluence Skins.

Any further advice?
