Hi guys, first post on here, if this is in the wrong spot please let me know..
I'm having issues with a GH60 I finished assembling recently..
All keys tested fine before soldering (starting to doubt myself on this), and all keys work fine except ROW4 (shift, z, x, c, etc).
All keys on row 4 cause their whole column to register. Here is a screenshot of every second key being pressed to show you what I mean.

Any idea's what would cause this? Or where I should start trying to fault find?
Here is a pick of the board: (the brown is just excess flux I havent cleaned off yet)
