I *think* I managed to determine this was a purely mechanical issue with the switches. I used a plastic pry tool to press down on the top metal contacts of the SW2 and SW6 switches while they were in the on position and they work better now. Still not perfect: while putting them into the on position, they still sometimes very briefly output a low signal while they have already output high signal initially

I bought a Basys3 on Amazon and just received it. I've been playing around with it a bit and it's a cool device, but I just noticed a weird issue with SW6 and SW2. Their signal output is usually clean as high when on, but if I approach those switches with my finger within half a centimeter (even not touching them), that output becomes erratic, flipping constantly. (It's almost magical, if anyone has a definitive explanation for this behavior, please reply) I have found out I can get the same behavior from all the other switches, too, if I position the switch around the middle between on and off. This leads me to believe SW6 and SW2 have bad solder jobs or something, which makes them behave while in the on position as if it is set to the "middle" position (obviously, middle position doesn't exist as defined behavior for such a switch I guess). Is this a known issue with Basys3 boards, that some switches aren't properly functioning? Guessing I can't do RMA since I bought it on Amazon. Is this easily fixable by resoldering this myself? I happen to have hundreds of the exact switches used in the board from a project from years ago.
