Fixing text en masse after Rhino 6

Has anyone figured out a quick way to reformat the text that the Rhino 5 to 6 change unformatted. I have drawings with hundreds of text object been reformatted like this.

The one shown read


26 45 24-1/2

on RHino 5.

No solution?

Is it only default style? Did you try to change to annotation scale ?

The style is “Helvetica Regular” that ,must have been created as part of the V5–V6 conversion. It appears all text was assigned this style.

I have not tried to change the scale.
