Empty filter search result in segmentation

Hi everyone,

I have created an Attribute List to use for segmentation.

It turns out, when I want to add a filter, and I click on the attribute, then i press "Select filter", the pop-up that appears, doesn't show the available filters. 

But when I choose a standard Attribute List, and try to select a filter, the pop-up that appears, has all the available filters which can be used.

To create my Z attribute list, I have created the following:

1- An infoset as an exact copy of CRM_MKTTG_BP_CENTRAL

2- A data source containing infoset previously created

3- An attribute list containing the data source previously created.

I think there might be an option in the infoset creation, that I am missing.

Can anyone help?

Thanks!
