Single Block switch ignored

Great product. Really enjoying it.

Running the T41U5XBB board flashed from the web builder and ioSender .44
Start, Hold and Single Block buttons are hard wired.
I was testing a short program.
First I single block through the entire program and it stops at the end.
If I click the Reset button in ioSender at that point and cycle start again, it ignores that my single block switch is on.
Seems like I need to toggle it on and off before I start if I do a reset.

This has to wait until I am back home and have access to a board.
FYI when I tested with the STM32F7xx it works, and the code is basically the same...
