I have tried to work out what you have since L3 not used I will assume L1 is common this would mean old L2 = new L1 and old L3 = new L2. But we seem to be missing wires each red wire will have either a black or a yellow and blue wire with it and if thatâ€™s true then missing one black and one blue wire. The link may explain missing blue but still missing a black and when I checked a switch in my junk box common was L3 which would mean a wire has fell out? As a result I canâ€™t be sure plus normally L1, L2, L3 at the top of a switch would mean L3, L2, L1 at the bottom. Listing right and left makes it harder to work out what connection is what. It is very unlikely L2 is common but either L1 or L3 may be common and in practice I tend to look at switch shape as much as markings and if not sure I use meter. Sorry I canâ€™t help more if you can group which wires are from which cable then may be I can do a better job.
