Audio clips on timeline are displacement

Sorry i'm bad in english, i'll try my best to describe the question i met.

This is my timeline. purple line and blue line are duplicate frame marker. Right side clip was cutting from left side.
Normally when i open sequence, both side audio clip waveform shoud look like left side(in-out range), but now it's not.

I‘ve tride cutting again and covering right side and save, but it doesn't work.
Every time I open project, clips will show up like this.
Another weird thing is if i double click right side audio clip, try to chang in-out range, i coundn't change out point.

Out point seems be locked so i cant change out point.

Anybody knows how to solve this question?
