I found "lines drawn off-axis" warnings associated to your sweeps and several of them corrupted. I deleted bad ones and re-did one window trim and sill for you. The trim via in-place component sweep. Type parameters exist to control it's width (wt) and thickness (tt), and material (mat). Sill was done with Wall Sweep Tool using default profile you defined in project. Check them both out and see if you can see if you can do the remaining Windows.
TIP: before you draw the Profile for the sweep, right-click on the View Cube and select Orient to Plan and then pick "Reference Plane:Profile Plan" for your view orientation. It will make it so much easier to draw your profile. Also, start your profile by drawing x and y sketch lines, and align and lock them to the two Profile Reference Planes.

One other suggestion: you still have 2 warnings related to a couple of other sweeps in your project that I would NOT ignore. Delete them through Manage=>Warnings (Expand dialog box), and then redo them. The other warnings you have may be ignored, but it's best to monitor and resolve Warnings as you progress. Otherwise you could build warnings on top of other warning and make it impossible to delete or repair them later on.
