Thematic Height Display Legend

Hi all

I've displayed surface triangles as mesh and turned on the thematic height display style.

I've changed the legend to be not dynamically and I've changed the elevation range to a number of colors and the range values to every meter.

I've put the legend as a persistent element in my drawing.

The values of the legend displays up to 5 decimals. How can I change the number of decimals to be less than 5, f.e. zero decimals or 2 decimals?

Thanks for any reply.
