Boolean difference problem

I have a clock face that I am trying to cut the numbers out of. All was going well until I reached the number 4 and MOI refuses to cut it out, well it cut out half of the number and destroyed the rest. Any suggestions or workarounds. I have to use this font for it. So changing fonts is not an option. Thanks for any help
