Premiere Pro and Ableton syncing issue

Hello, Could you please tell me why after the sound engineer sends me an audio, which I use to make a video and then render the final result, the video together with the audio loses the first seconds (literally the attack or in other words the transient). And when I send this video back, then in Ableton my video with music does not start from the very beginning, but after a few milliseconds. This is very similar to autofades or crossfades, which are usually enabled by default to avoid clicks in DAWs. Or is the reason in something else and I need to disable something in the settings? Any ideas? 

Please find attached Blue audio and yellow video screenshot as well as duration of cut..
