Mystery wall framing generated from...nothing?

[ChiefTesoroTX]

There are three spots in my plan where framing members (studs, plates and fire block) are being generated in odd patterns, with no perceivable reason for them.  I've tried enabling all layers and selecting in these areas, two of the three are several feet outside the house with nothing else there.  Has anyone ever seen this before and could shed some light on what artifact or sloppy configuration I probably left behind to cause these to appear?  If I delete them and then rebuild the framing they always come back.  There's something odd about the way they are placed.  I don't know how I'd even create these if I wanted to so it leaves me without a clue what to look for.

Do you have any walls on hidden layers?  They will still get framing even when you can't see the wall in plan view.

 

You should probably post your plan for problems like this.  Might need to make a copy and delete a bunch of stuff to get it small enough to attach to the forum.  Should probably zip it as wall but you need to make sure the plan is not open when you do this.  Another thing you could do is post in on a cloud service to share.

It was a duplicated wall legend, including one that was on the second floor intersecting with the garage.

Wall schedule placed in a Cad detail. May help on this.
