If the text style in your dimension is associative, you can't change it in the dimension style. Use a style that isn't associative, or make a copy of the associative style and change it to non-associative.

 

If that doesn't resolve your issue, please provide more information or a relevant excerpt from your drawing.

If there's a Height set in the Text Style it will override the Text height in the Dimension Style.  Use a different Text style whose height is set to 0.
