Ambika multiple LED's lighting up!

Hi.Happy New Year to you all
I’ve just completed my first Ambika motherboard. The functionality during testing seems fine apart from one thing. Pressing switch 8 results in LED’s 8,9,10,11 & 12 to light. I suspect I may have fried some shift register but before delving deeper thought I would ask the forum if anyone had encountered this before. Comments and suggestions please

That’s normal. This corresponds to which of the 8 buttons have a command assigned to them in the load/save menu.

Thanks O. Maybe its time for me to put down the assembly instructions and pick up the user manual ! Great to know my build is all okay though.
