error in dimension DXF

I get the following "error" when saving a sheet to dxf-extension.

See the following pictures..

When I convert it to DXF;

If I set the fonts to true-type in the "save-as-DXF-options" there is no error,.. but anyone knows the solution for the error when saving with standard autocad-types?
