Firmware 2.1.2 has been released, which fixes the above two issues: 1) /jp returns incomplete data when the number of programs is a multiple of 3; 2) incorrect handling of the SPACE character in program name. 1) is likely due to a compiler bug, and I am surprised that it wasn’t brought up earlier.
Anyways, thanks for reporting the issue. If you have never upgraded firmware before you can check the instructions here:
