I've previously gone through and updated the WHOIS information following the procedure noted above weeks ago, but it does not update the information in the main WHOIS database.
In fact, when I click on the domain, I see the old information. Once I click on the Modify WHOIS info for domain I see the new information. But once again it is not shown in the first screen or in the main WHOIS database.
There must be something blocking the transfer from your end to the WHOIS UK database.
