Set Value functionality does not reset itself until you force it by specifying "No Value" and pressing OK (even though "No Value" is already selected)

Drag a loinc code into a query and run a patient count. Result will be x patients.
Drag the same loinc code into a new query and right click on it and choose "set value". Then choose some numeric restriction that restricts the number of patients. Result will be y patients.
Start a new query and choose the same loinc code with NO RESTRICTIONS and run the query. It will NOT return the total number of patients. It will return y patients.

WORKAROUND: Any time you want the total patient count for a numeric value, always right click and choose "Set Value" and choose "No Value" and click ok. This resets the webclient so you will again get x patients.
