Can't use API Management service on Bluemix

I'm trying to use the "API Management" service on Bluemix, but I have the message "Not fetch data plans".. so I can't use the service

I'm trying to change the country or region, but it's always the same message. I need help clarifying what causes this problem.

Solution

I had the same problem with Firefox as the browser and German as content language. The moment I set the language of the browser to English, the plan details on API management appears and I am able to create the service.
