Placing part in Assembly but it is out of date?

[The One]

Hi,

I'm in the middle of an assembly and there are two parts that when I place them they are out of date, and I can't get them to update?

I might add that they are the only two parts in the whole project that were made with "Sweep" command?

Also all parts were drawing out in AutoCad, copied, saved and then "Project Geometry from DWG file".

Thanks.
