It's look likes the Filter Application isn't working properly. Even when I select one category to be filtered, it's keeping showing the full list. I could noticed too some "logic conflicts" in the Filter. For example:
I have two jobs. One is AutoCad (IT category, 3 star rate) and other is Head reception (Hotel category, 5 star rate). So, if I go to the Filter Options and select:
Minimum Rating: 3 star
All the rest I leave blank.
When I press Filter Applications, it still return both applications.
I hope that you got it here :-)
