It too have a bad catch on mine. It doesn't quite hold the panel causing it stick out by about a millimetre, so it doesn't sit flush with the door
I've had the same problem twice, and both time Phanteks have sent out some spare clips the next day, but I'm now waiting for set 3, and they have a new revision to them and have been changed, they are sending them this time. I've had a few problems like the front led strip, and fan hub have both failed they too are on there way.
I'll report back when the rev 2 clips arrive.
