Output Expander not Mirroring 2 strips

Hi @LostPanduh ,
Version 3.47 reworked how the drivers work and it no longer supports overlapping or missing pixel indexes. You could downgrade to a previous release, and then set your channel 1 start index back to 0, or do some tweaks in pattern code and/or pixel map to make it overlap that way. Sometimes you can also use one data line output to drive two LED strips.
