In a landing flare, you want to raise your negative V/S to near zero. A positive vertical speed means you're no longer descending, but ascending. Having a positive vertical speed during the landing flair is something you don't want to have as you're basically floating (and possibly climbing) above the runway and bleeding your airspeed which, in a couple seconds will most likely end in a hard landing as you've stalled while floating over the runway.

The positive rate of climb to me, indicates that they attempted to climb (go-around) but their low airspeed resulted in a stall.

It's important to remember that this data was pulled off Flightware which is basically aggregated data. and not from an accurate source such as the FDR. So my guess could be totally wrong.
