Query Component Save bug

In the same application bellow i try the Save... button


Since i usally want to query employees with salary >3000 i set that value and i save search:


But when i run that saved search i dont get the result, the value of criterion is lost:


So i thought ok it doesn't save values, lets see advanced search:
I use advanced search and add Salary again with same value.
I save criteria and now it saves both criterion and value:

So it doesnt save criteria values that have bind variable.

Yet i wouldnt know how to explain this to an end user...

Is this a bug?

No? since it has a workaround?
Dont use bind variables in criteria?
