Floor joist issue

I have been going through this plan and i can't figure out why the floor joists always frame as I-joists. I have set the defaults and room floor structures, everything i can find.
I have turned off auto framing. I can change individual joist to framing but they change back when I reframe the floor.
And why is my subfloor sheathing showing as strips on top of the joists?
I know this is something simple again but I can't figure it out.
I am using x17, (I know I need to change that in my signature).

I haven't got x17 loaded yet.. but I can answer this.  Go to your floor structure definition, item 1 should be your sheathing.  Make sure "Framing" isn't checked.

 

Matter a fact, this same dbx, see how your item 2 should be is marked.. this determines your joist style.

Ahh... you have to do it for each material. Dang. I know I have been through this before, hopefully I can remember next time.
Thanks Michael!
