Inserting into project at cursor from pool

I’m having a problem with concatenating wav files together. I’m making an audio track, import a bunch of wav files into the media pool, then I’m taking each one and doing a “Insert Into Project > At Cursor” command on it.

Certain wav files are not being inserted so that the beginning of it is on the cursor, rather Cubase is inserting it so that the END of it is at the cursor and it’s overlapping the previous one. On top of that, when I try to correct the problem and move it so the beginning of the wav is at the end of the previous one, the event snapping feature no longer works! It’s like Cubase just goes stupid.

Is this a problem with the wav file or something?
