I am going to guess you dislodged the stabilizer mount. I did that once on my Leopold which caused the key to sit oddly like that. It clips into the pcb, but the problem is it is under the plate so it can be hard to see. With the keycap off, can you move the stabilizer towards the fkeys or enter? If so you are going to need something quite small to use to press the clips back into the pcb.
