Re-stringing my 2500

[play4zero]

For some reason, nothing seems to be working on my 2500 the way it should.

I just changed out a set of Curt Mangans and put a set of Rotosound nickle swingbass strings on it and all of a sudden I have tons of relief that won't seem to go away. In addition, I loosened up the little allen screw that holds the bridge saddles in place,because they all need moved over, and even though I took the little screw all the way out, the plastic piece holding the bridge saddles didn't budge a bit. Any ideas?

Sorted out the relief problem, but the bridge is still a puzzle to me. The spacer that's down by the G should be up by the B.
