Sharkbook - matching sharks across oceans incorrectly

Hi, this is a definite bug. As you know, the grey nurse shark species has separate populations that never meet (and have not done so for thousands of years). In the below match, it tried to match a shark from the East Coast of Australia to a shark in the US.

Please can you ensure that East Coast of Australia sharks ONLY match to other sharks from the East Coast of Australia. And that West Coast of Australia sharks ONLY match to other sharks from West Coast of Australia. Same for South Africa and the US - they should only match to sharks from their geographical area.

Please see attached the error spot map. See modified groth results number 11:

Weirdly, despite the match candidate locations appearing above the match table, there doesn’t appear to be a way on the user side to edit which locations are matched against. This doesn’t appear to be a bug, just bad design.

I’m going to change this to a feature request. I’ll follow up with a ticket soon.
