When loading .iso or .mme I see an empty list in the data portal

I everyone,

If I load an .iso file or an .mme file, in the data portal the name of the file will appear, but there won't be any channel under it.

I imported the plugins for iso and mme:

-EGV files.uri

-DTR13499.uri

-MME import.uri

See attached picture for better understanding.

Any help would be really appreciated
