Test value in advanced recordset

HI

In the binding recordset I have a filter looking for a date matching the URL parameter. In the simple panel, a valid test value returns normal data.

Unfortunately, testing my web page does not returns any data.

In the advanced panel of the recordset, testing the same query does not return any data. This is matching the result I have in the web page.

1) Why the advanced test panel does not require a testing value.
2) Why the 2 testings does not return the same results.

Thanks
