It's only warning, skin show the flag image when image filename in resources is 100% equal info available in Kodi database, if don't exist the image filename or name is distinct in resource when compared with info available in database, show the warning.

Ex:
Action Genre

To show Action flag image, need have Action.png available in the resource, now imagine item in database was translated to portuguese to Ação, so Kodi compare Ação and don't find filename Ação.png, so one warning is generate to say look don't have one filename available when Kodi compare one with other.

How solve:

Including new images to resources add-ons or changing the art image filenames.

Yes, ok, but we do not get error for 1 file, for example "DoWork - Direct texture file loading failed for resource://resource.images.studios.coloured/Action.png or xxx.png".
We get an error for the whole folder "Direct texture file loading failed for resource://resource.images.studios.coloured/".
And what about the missing /flags/resolution etc. warnings?
Also why do the other skins do not have these errors? I'm just asking at of curiosity.
