Choice boxes problem. Easy fix? two word answer automatically get an underscore

Be gentle I’m new. I’m having a problem with choice boxes. When you have a two word answer it is not recognized. It’s probably something simple. Any ideas?

can you put your screen shot of choice block settings?

what are the block settings?

when i type in the two word answer im looking for it automatically puts an underscore in between the two words. when you say the words it does not produce an underscore.

if i manually type in the two word answer with the underscore it works in the test.
