I guess that's what you get for buying it untested? I think it was genuinely untested as all the batteries were showing 1.3v instead of 3v. It might be the fact the batteries are rubbish I'm not sur.e it's odd as marked as it's rated for 6v but you put in 4x3v batteries.

Does it only use two at once or limit the voltage?

I wonder if a good clean will do it any good. If not I may send it to YouTuber mymatevince!

Oh yeah, if your batteries are reading that low, that could definitely be the problem. Have you tried a fresh set? The 6V rating might be for an external power supply, but that's just a guess. One of the four batteries is for memory backup, so the main batteries would be 12V if they're connected in series (also no clue about that, I'd have to poke around with my multimeter).
