If you place a regular section at the exact same location as you interior elevation what do you see?
If it is the same then it must be something to do with you objects and elements making up the model.
If it is different then it is probably a setting or possible bug with the interior elevation tool.
The IE tool has had its problems in the past (and still does I believe although I think it is improving) and these may not have been resolved in version 15.
Personally I have never used it which is why I suggest trying a regular section to see if that is OK.
