Issue with min and max values for Salary Basis + Default element value doesn'twork

Content

Our Customer doesn't want to use Grade Rate functionality but asked us to set up Min and Max values common for all employees (just to check the mistyping issues). 

I've determined Min and Max entry values validation for element releated to needed Salary Basis. WHen I'm hiring the employee the system gives an error when I'm putting the value outside of this range (as expected), but when I'm changing the salary to correct one it continues with errors and doen't give me a possibility to Submit transaction. In the same time when I'm entering correct value from the first time there is no issues with Submitting the transaction.
