Kathi,
Hello again! I just updated your support case but I thought I'd chime in here as well! You most likely have the field type set to Boolean (true/false) so when you enter in ANY value into the field, the system just sees that as a "true" for the presence of a value.
If you were to change that field type to Integer, it would then pass on the actual values the user/lead selected on to the field correctly.
Hope this helps and have a great evening!
Jesse
