[Observium] Incorrect Port VLAN Information

I'm testing out Observium and I've noticed a problem with some of the VLAN assignments. Our shop runs HP Procurve switches and we've seen this problem on both the 2824 and the 5308xl.

Here is what Observium sees vs the switch config: http://pastebin.com/FGC4z8eJ

Is this a known issue?

Thanks, Casey
