Attr Set not available in component

Hi Gurus, I am having some problems with add som fields in a componet.

I did exactly the same what this blog say

http://wiki.scn.sap.com/wiki/display/CRM/Creating+UI+Configuration+for+Set+Types+to+display+on+CRM+Product+Overview+page

The thing is when I do all this steps I cannot see my z attrset in my component PRD01OV.

I have noticed that I have 20 displayed assignments blocks, and only in my view I can see only 9 .

Does anybody knows how could be the problem?

Thanks in advance.

Regards
