The same thing happened to me kabayan. I think someone is not doing they're job well in BIQ-HK. I mean, for people with two degrees it just keeps on happening. I'm also a nurse and a biology graduate but I've applied as a nurse. They sent an intent to reject my application due to lack of points but eventually after I asked for a recomputation, they've finally sent an email for my interview. You'll make it, don't worry too much.
The only thing that's messed up though is that they've eventually wasted a good four months of my application time and the money and resources that I've put on for them to reconsider my application again.
In the need though I hope we'll all be rewarded. Be patient. All is not yet lost.
Cheers!
