I never use the dual digits below 10, and never have seen this problem.
Simply use 1,2,3,4,etc. through 9.

I believe this would rerlate to the windows numeric system, not any bug in Microstudio. Not that I can't be wrong, just my guess.

Never seen the dual digit's below 10 on any commercial cassette or cd contents listing either. Maybe that's the reason these days, since everything's computerized.
