Windows 7 Finale 2014.5

I've got a three player percussion section (so three separate percussion staves), one of whom will be covering wood block and tambourine (for starters). No matter what I do, I can't seem to add a wood block in to any of the percussion maps and get it to play back. I've added the note in the MIDI menu, I've added it to the percussion map in Score Manager, but no luck.

This is a transcription for concert band of a piece originally for orchestra. In the original I seem to have done a workaround with claves from the Marching Band map, but I can't seem to find that option here.
