Audio is cutoff on sample playback of import window as well as timeline after import even if source file is complete

I’m having this strange problem and I don’t know what’s going on. I have been trying to import several mp3 files onto a new project but it appears to be missing several seconds in the sample playback engine of import window as well as project window timeline after import. The source files are complete when I play it back in windows media player and other players as well. The imported files in the audio folder has been cut off by a second or two. I have been trying to re-import, restart PC and Cubase but still having the same result. Please help me. Thank you very much.
