Somehow that looks normal to me.
The recommended work flow is to get your video clips arranged and edited, and then import your audio clips. Otherwise, as you have found, it is a mess if you have a lot of rearranging to do.
I suggest that you select and Edit/Copy your audio clips in the project, then Edit/Paste them into a newly created auxiliary project. Then go back to your original project and arrange the video clips. After you finish that, go back to your auxiliary project and do an Edit/Copy, Edit/Paste, of the audio clips back into your initial project. Then you can easily arrange the audio clips to sync with your video. Do the audio editing in the lower audio well and you can move them up later if you want.
