Hmmmmmmmmmmmmmmm....

As Woks pointed out, the grooves on some of the saddles are offset.
Check that the correct saddles are in the right place, sometimes these can be installed incorrectly.

Next step is to try and clamp the bridge in place using two clamps and a chunk of timber spanning the width of the body.
Then re check the string to edge of fret board gap.
This should be 4 mmish on the B and G strings.
