Audio waveform in timeline won't update

Hi, I have a problem that already fixed by myself but better if it's fixed by the developers.
So when i update my audio on a comp and then go outside the comp, i see my waveform still used the old audio waveform not the new audio that i just puted in to the comp.

The solution is to turn off and then turn on again the audio icon on the comp and then it fixed, the audio waveform just updated.

i Think the old version doesnt have this kind of problem before, so please help us fix this little bug, cuz this bug sometimes anoying for who dont know yet.
