Odd wiring issue

So I've encountered an odd issue while swapping the pickups in a Chapman Ghost Fret. (2 Humbuckers, 1 Volume, 1 Tone w/ Coil Tap, 3-way toggle)

Here's the issue-
After installing and soldering, with the bridge pickup selected, all is well and it behaves as it should. Push/Pull in the down position gives you the full humbucker and in the up position it taps. Perfect.
With the switch in the neck position, I thought I had done something wrong because I wasn't getting a lot of output. I figured "if it sounds this weak now, how would it sound if I tapped it?" so I pulled the tone push/pull for ****s and giggles and to my surprise- the output doubled. So it seems like the push/pull works in opposite positions between the neck and the bridge pick ups.

TLDR;
Switch in center position, Push/pull in down position- taps neck and leaves the bridge as a humbucker.
Switch in center position, Push/pull in up position- neck is a humbucker, bridge is tapped.

Anyone have any ideas or experience this before?
I followed the respective SD Diagram:

I've tried doing a complete rewire with new pots and caps. Also tried swapping the neck pickup thinking it may be faulty but I get the same result every time.

Any help would be massively appreciated.

Do you have a multimeter? I’d check continuity on the switch contacts for the push-pull.

Technically, that should be impossible. Did you, by any chance, get one of these types of push-pull?

Slim to none. More likely bad solder connections. I'm not questioning your skill, but soldering is an art. ;)
 
Re: Odd wiring issue

The only way I could make a normal DPDT on-on switch behave like the description is if I wired the ground at opposite corners of each side of the switch, or wired the red/whites to opposite corners and used the center lugs for ground, but in either case, one pickup would always be split - you could never get both as humbuckers. If that is indeed how it's wired, then it's not wired like the diagram, or the pickup leads were done wrong.

What pickups are these? Are they even Duncan pickups? (Different manufacturers use different color schemes for the pickup wires, so a Duncan diagram will only work for Duncan pickups). Are these new pickups? Or did you buy used?

SD Black Winter and a SD Custom Shop.
Also tried a SD Jazz neck.
