[NX 12] Ordinate dimensions create extension line at origin

Good day,

I'm running into an issue and I can't seem to figure out how to solve it.

In previous versions I can't recall this happening.  It started in NX 12.

When creating an ordinate dimension, I can select a previous origin to add new dimensions from the same origin.  That still works fine.

But when I add new dimensions, NX creates an additional extension line at the origin, and I can't hide or delete it because it hides/deletes the dimension I want to keep as well.

See attached:  I have selected one of my ordinate dimensions, and you can see that it also selected the additional extension line that is coming from the ordinate origin.  It treats them as if they're both parts of the same dimension.

Is there a way to turn the origin line off?  I can't seem to figure it out.

Thanks for your time.
