I see what you mean, but that is not a glitch. I've used Sprite 0xCC for this !-switch, so it will not reappear once you leave/use it. Since it's unlikely that anyone would leave the room without pressing the switch and it's pretty much at the beginning of the stage, this doesn't seem worthy to be "fixed" to me, but thanks for looking for issues anyway.
Also, I've encountered a thing in 6-5, which cannot be fixed: In the room with the blue deadly spikes, the watermelon and the Lunge Fish, the game will freeze, if you shoot the ?-cloud with the POW at the same time Yoshi gets eaten. He won't get K.O., but he will remain underwater forever.
NEW! SMW2 Yoshi's Island is done!
