Bug on map - BIOT

Hi, there is something wrong with the map - I noticed that British Indian Ocean Teritory (BIOT) is displayed on the same colour as UK, even I don't have any coin from this teritory in filtered collection. I know, this is part of the UK (or maybe no more, but this is not the place to discuss this topic) but normally, teritories are coloured only if you have coins from these teritories. All other British overseas teritories are not displayed. Not sure why BIOT is.

Not a bug but by design. It's based on how Numista orders the issuers.  That dot is for both issuers.

Same for Puerto Rico:

And many others.

But why only BIOT and not for the example BAT, BVI, Gibraltar or other that are together under the United Kingdom & teritories & dependencies?

Hmmmm…I see. I don't know.

They are not automatically colored depending where they are on the issuer hierarchy that all has to be set manually and somebody either has or hasn't done only that one island.
