Corrupt Template.dwg Errant Surfaces in "Sample more Sources" Dialog Box

[dj112358]

Potentially corrupt Drawing Template.  Multiple Existing Surfaces  are found in drawing, but not in the Toolspace Surfaces list.  When I create an alignment, profile, sample lines, and then section views, in the "sample more sources" Sample Line Group Properties dialog box, there are multiple existing surfaces.  for example:

EXST (4)

EXST (18)

EXST (9) (1) (1)

EXST (6) (1) (1) 

.

How do I get rid of these errant surfaces?  Is there some sort of purge command?  I have included a sample drawing with an alignment, profile and section views created from my template.  I tried to include my template, but this forum does not accept .dwt formatted files.  They can be found in all of my drawings so they exist already in the template before I begin a drawing.

I'm not sure how to remove those surfaces. Wblocking the dwg into a new template doesn't remove them and neither does creating a New Sample Line Group.

When I delete the section views from the drawing. All of the sections your seeing appear under the Sections in the 0001 Alignment and can be deleted

rl_jackson,

When I delete the section views I'm still seeing the multiple EXST* surfaces in the "Available Sources" listing.

Same here thought I had stumbled on to something

Begining to think it may be a corrupt site.
