Virtual Bundles not working

Hello there - I wanted to try out the "virtual bundles" feature so I can sell two slightly different products together, however when you click on the link via Seller Central UK it doesn't work. I've tried accessing it from other areas but still no luck.

It appears to work for Amazon.com though.

Any ideas why the link might be dead? Feels to me like they have the wrong link in there. (link below)

Not sure it's worth opening a case.

Any help would be greatly appreciated.

thanks!
