Need help! Weird CycloneII LED assignment problem!

Hey guys, My pins on board don't work as what they should do according to pin assignment. In my design entity, I have outputs LEDR0, LEDR1... LEDR5. I assigned them to correct LED pins, no...

What's your device option for unused pins? It may be e.g. "output drinving ground". Apart from changing this option to "tristate with pull-up" you should generally define unused but connected pins in your design top and asign correct pins to them. It's meaningful in my opinion to have them ready for later use.
