Jewels of Osirus doubled gems (glitch)

Jewels of Osirus doubled gems at the bottom… and it looks like a green gem is active, behind the hex violet gem, in a row of green gems…I could not move the top gem. It is circled at the bottom of this screenshot.

[edit] There’s a blank space, in the middle top, where the top violet gem is active.

I have seen this too @DukeNukem. I’ve also seen it right itself when a move elsewhere on the board causes a cascade that affects the slipped gem’s actual position. If that doesn’t happen then I look for a way to play the blank square out
