Mayflash GameCube Adapter only recognizing 2 controllers at a time

[DabScience]

So I recently purchased a Mayflash GameCube Adapter for Wii U and PC.

I'm currently running Dolphin 5.0-78

To start I should explain that I have always been able to use two GameCube controllers but the input ports have never matched the device. As you can see here, controller port 1 has to be set to [DInput/2/MAYFLASH GameCube Controller Adapter], which should be the third port on the adapter but the controller is in fact plugged into the first port.


At this point I realized my MayFlash adapter ports had switched port 1 and 3 for no reason?? Plugging into port 1 gives you DInput/2/, as I already stated, where as port 3 is DInput/0/ which should be port 1.

Now that really wouldn't be an issue if I could still use all of the ports, but as it stands I can only plug in and receive feedback from two GameCube controllers at a time. As soon as a third controller is plugged in, Dolphin fails to recognize it. I switched the controllers around and made sure they we're not the issue. I then tried using a wired Xbox One controller as a third controller and it work flawlessly.

It's been about two days of my trying to troubleshoot this myself and I could really use a hand. Any help is much appreciated!
