Bad screen adhesive after crack replacement

Recently I had to get my screen replaced on my newish MBP after an alarmingly short drop onto the carpet from a couch arm cracked the screen rendering it unuseable. As the local official apple repaired had quoted my over $1K (And apple definately would not warranty it for me) I used a joint nearby thaqt had quoted a fraction over $500. I had used them in the past for repairs on the old macbook (Im a clutz) so they are usually pretty good.

The macbook came back fine, however it seems the screen isnt quite attached in right and sometimes sort of flops out of the case!. Peering behind it it seems theres some what LOOKS like magnets, but also there seems to be some sort of adhesive that really isnt adhesive at all.

How can I fix this? Do I just need to get in there with some super glue, or is this something that needs a bit of finnesse?
