Disabling inventory storage in the UK

Dear Community,

We're trying to disable inventory storage in the United Kingdom as a EU seller, but we cannot find a way to do so.

When we checked under Settings → Fulfilment by Amazon → Cross-Border Fulfilment Settings → Enable Inventory Storage, I noticed that the United Kingdom is still listed as an activated country.

When we click the Edit button, it redirects me to a PAN-EU page, but there is no option to disable the United Kingdom as a storage location.

I seem to recall that a few months ago, it was possible to deactivate it directly from this section. Our source marketplace is Germany.

My question is:

How can I now disable the United Kingdom as a storage location to resolve this issue?

Thank you for your help.
