UID number for Switzerland

Hello experts,
I am trying to add Switzerland UID number in BP transaction and I am getting this error:

And this is correct UID number since I picked it up from official site:

I tried entering it in different formats:

CHE-141.944.256 -> same error

CHE141944256 -> just says "Tax Code 1 is not valid"

I found out that many people faced with this problem, or similar one, but I couldn't find any results.

Can someone resolve this?
Thanks in advance.

Best regards,
Luka.
