5.5.3-Import Audio File-Waveform Envelope before

A recent problem :

When I Import an Audio file into a blank default project, the envelope of the waveform begins before Bar ie. the actual start of the envelope is “hidden.”

When I import more than 20 SFX at a time, some are positioned exactly correctly with the start of the waveform exactly at, while others I have to manually move and then “reveal” the start of the envelope.

I must have a preference that has accidentally been reset or changed. Can anyone help ?
