The .ttf font file in the new version of chief blueprint was changed in spacing. So here is how to solve the problem:
1.go and copy font file of older version of chief.
C:\Program Files\Chief Architect\Chief Architect Premier X6 (64 bit)\resources\fonts
2. paste the .ttf (font file) to
C:\Windos\Fonts
it will ask you if you want to overwrite the file. click yes to replace it.
Restart your program and it should be back to normal.
if you can't find the font file message me and I can email it to you.
