Filming locations in overseas territories

Hello. I have come across a problem where my filming location suggestions have been rejected. I usually have no issue when submitting locations for places in the United Kingdom, France, USA, Germany etc. However, I have real problems when trying to set up locations in overseas territories such as Greenland, Falkland Islands, Isle of Man and Jersey. My submissions are usually rejected. I cannot see any guidance on how to submit these. Recent examples have been:

Jersey Zoo, La Profonde Rue, Jersey

Christ Church Cathedral, Ross Street, Stanley, Falkland Islands

Nuuk Stadium, Nuuk, Greenland

Can anyone suggest why these are rejected?

Many thanks

Carl
