K21 Blue Feet fused to shelf?

This may sound odd, but I just attempted to rearrange my equipment and discovered that my G4 K21 seems to be fused to the shelf. I aborted the move for fear of damaging myself or the shelf.

It has been sitting in the current location for less than a year. I’m not sure of my next move; really don’t want to remove the finish from the furniture.

Anyone else experience this? Ideas?

I’ve found the new feet can get stuck with suction to the shelf, not so much that it’s an issue on my K30.
