Hi - One of my dimension styles is now dimensioning at 1/4 the correct size. 

I have purged the drawing. I have tried deleting the dimension style but I can not seem to delete this dimension style as it is in use in the drawing. 

Short of re-dimensioning everything, and creating a new dimension style is there anything else to do? Is there a setting that somehow changed in this dimension style?

Thank you!
