ImportDimStyles fails on at least one style...why?

V4 I use ImportDimStyles I browse to a rhino file with a style called Dimension Style 01 which has 15mm tall text
It shows three styles including this one all ticked so I accept all three.
I go to properties and select Dimension Style 01 to start using it and see its text height is 1mm and other values I had changed are not there.

I dont see the advantage in this command if this happens.

How become this one failed yet another there was ok ?

I havent done an in depth study to see what else fails, I wanted the 01 style.

How should I import my dimension styles ?
