There is definitely something wrong. I am having the same problem: A clip which is actually 29.97 fps (verified using QT properties) is importing as 1/2 framerate, or 14.985 (rounded up to 14.99) fps. This happens with several of my clips, regardless of the import method used (drag/drop from OS, right-click/import, or use Media Browser). I cannot interpret the footage back to 29.97, as doing so doubles the speed of the audio (an interview), making it unusable.
