Bionic Commando PCB - kind of weird stuff I've noticed

So I bought a Bionic Commando PCB awhile back and it works. I'll be able to play through all 5 levels and then start the second loop. That's when weird stuff starts happening. Enemies from the 1st level... like the green birds... will be on the second level. There are also spikes on the second level. I don't remember there being either green birds or spikes on the second level.

I was playing MAME and I didn't see where this is normal. Is this expected behavior with a certain DIP switch combination?

Also, I've noticed moving to the left sometimes doesn't respond. I have noticed this same issue on MAME. It doesn't happen often just once in awhile. Does anyone know if this was just a bug in the game or what the deal is there.

Is my PCB a little off its rocker or maybe something else?

Tested the power supply and it reads

4.98
-4.83
13.63 = Is this a little high? I tried to tune it down, but when I adjust this to 12 the 5VDC goes too low.
