Parts not showing

[garrett]

I imported my model and only two parts are not showing.  I cross-referenced them in Rebrickable and imported the DAT files from the official page.  But every time I upload the file they still do not appear. 

part: 93609 and 49308

In what program do they not appear? And from where was the model imported?
