Featured products - number of products

[LCortes]

Dear all,

As I told before I don't have any programming knowledge, but before (and after...) I post a doubt, I try hard to solve it myself.
In this case, I couldn't find a solution, and that's why I'm asking your help:
in feature product module, the default number of displayed products is 8. When I change it to 4, the front page still show 8.
Is that a error code? or should I change anything else?

Thank you all

Once again, I will answer myself, because may help others resolving own issues:
in my case, I just uninstall the module and install it again.
worked like a charm.
