Domain for 2nd market keeps redirecting to main domain

[MarkHolland]

Hello,

I have an online shop in the Netherlands and have now added a second market to my store for the UK market. For this market I've registered a seperate domain, and now I'm trying to point this domain to this market.

It all seems to be setup correctly, however when I go to my second (new) domain www.buyemergencykit.co.uk, it keeps redirecting to my main domain www.preppack.nl.

It does put a value in the url like https://www.preppack.nl/?shpxid=2eb9452f-4223-4a0c-8dad-c8c0bfc54bd0 for example.

The weird thing is, that if I then try to visit www.buyemergencykit.co.uk again it does go to the UK website like it should do??? I tried deleting cookies, using different browsers, my phone, asked other people to check. But same everywhere.
