JU-475-5 won't read or write C64 side 2 of diskettes

[visualmess]

I have the JU-475-5 drive and followed the settings you have for this model from your 5.25 Jumpers PDF. I am able to copy side 1 of any C64 disk but it will not read side 2 or write to side 2 even using Splice and Index Read and Write Ignore when I flip the disk over. I thought this was one of the drives that would be able to copy side 2 ignoring the index? Have the following set in SCP when I flip disk and try to copy side 2

Drive type - (5.25" - 96tpi)
Weakbits - (Fixed)
Density (Read - Low), (Write - Low)
Index Sensor - (Read - ignore), (Write - ignore)
Disk Types (C64/128)
Copy Mode - (Splice)
Revolutions - 2
