Query is missing custom data fields

Hello,

we scan our clients for a specific registry key. This works good. When I look at the inventory of the clients I can see the key and its value.

But trying to create a query on this key fails. In the query window I cannot see this Custom Field. The Custom Data field is double and it contains only one value. But no Internet Explorer, no MDAC and not my custom field.

I want it back! Any ideas?

Thanks
