I tested EPG loading for your location. Indeed, there are a few channels missing from downloaded data.
Channels DR3 and Fyn HD do not appear in the channels list. Channels DR K and DR Ram do appear in the list of channels, but currently there are no programs associated with them.
There are more than 100 channels in the list, I wonder if DR3 and Fyn HD are just named differently? I do not know about Denmark, but here in the USA this is quite common. For example, the local NBC affiliate is named "NBC5" but its call sign is "WMAQ". When downloading EPG data, the name "WMAQ" is used. As a user, we have to know "WMAQ" is the same as "NBC5".
