The error report shows that you are missing a fill that is being called by the window macro. If you can open the window part and find out what the fill name is, perhaps you can just add that fill (using Attribute Manager) to your current plan from a past project or newer template. If you are using an AC17 wall, and an AC17 window along with the AC17 template, this may be a bug. However, if you are using an older plan file to start with, it may not have all the fills that the AC17 parts are looking for.
