I have Ice Show, the Add-a-ball version of Ice Revue, and it does not do this. Each numbered target is separate.

However, I did discover a similar error when I first shopped my machine years ago. Two of the six numbered roll overs at the bottom of the machine would go out if either one was activated. Drove me nuts until I discovered a wire had been installed between the switches to make the game a bit easier. Once I removed the wire everything worked fine.

Those upper playfield targets can be tough to hit with those little flippers. Is it possible that something similar has been done to yours? If not, I would look for a short in the associated wires.

Good luck!
