New Merkur Progress blade alignment issues, is it faulty?

So here's a album of the head and a couple of measurements of the gap on either side. I'm getting around a 0.2mm difference between each side even without the blade. Last one is the intense razor burn and weepers I got from my shave with it, a day after shaving.

Contacted the vendor and was told that I need to make sure to load the blade straight and I have tried and tried but can't get it to shave well.

Am I right in thinking this is faulty? I'm pretty new to wet shaving. Have a DE89 and a Qshave adjustable and never had a shave this bad with them.
