What is the data type? My supposition is that the data type is set to unknown.
If that is the case you have several options.
One would be to select the parent query subject and choose tools/ validate object. Another would be to open the query subject and press the validate button and then press the OK button.
It is possible that, when you select the query subject, that the status property will display the state 'Needs reevaluation'.
