Hi, I'm replacing a set of 4 switches and I did something wrong and now the lighting is all messed up. See attached for a diagram. The 2 switches on the left are 3 way (and the matching 2 switches on top are fine, I did those first and it all worked until I replaced the set of 4). The 2 switches on the right are simple 2 way. No matter what I try, at least one of the 4 doesn't work properly, and now I'm so far from the original wiring I don't know how to get back. Any help is appreciated. Also, the 4 white wires are tied off together in the back.
