Re-aligning front end after air con condensor replacement.. HELP!

On bank holiday monday I took on the task of changing my air con condensor due to it failing on my 2006 Octavia vRS 2.0T.

To complete this I had to remove the lock carrier/crash bar from the front of the car to be able to access the front of the rad pack. When it all went back on I lined it back up to the original 8 bolt holes where it had been placed previously (marked the position before removal) and for some reason the part of the bumper under the passenger side headlight is refusing to sit correctly and is probably about 5mm out which is leaving uneven looking gaps.

The bonnet shuts and opens fine and the gap from the bonnet to the centre of the crash bar is spot on! One thing I did notice is that the bumper rail which runs under the passenger side headlight wasn't sitting flush on the lock carrier/crash bar like the other side so when the final bolts are being applied I think this is what is dragging the bumper down to its incorrect position.

Any ideas how I could go about re-aligning it? Open to any suggestions!
