Missing SUBSCRIBES in d.tube - is there a fix?

Hi every

I have a question about d.tube

I have a subscription and can login. However, when I subscribe to someones channel I do not get a SUBSCRIBES entry in the menu on the right.

I know I had it the first time I signed up but since the second time I logged in again it disappeared.

What could be the reason for this and how can i fix it?
It does occur in IE, Firefox and Chrome.
