I think it's using the precision of the document's units setting.
The weld bead is all around, which automatically adds the all around circle to the weld symbol. Maybe the arrow is forced on because of this.
Just a thought.
I have my units set to the 4th decimal. I'm not sure what is was, I had to go in and re type the properties into all my weld bead. And now I don't have any issues.
Thank you for your time,
