If you are lucky and did not record clipping out of the dj mixer simply turning it down will fix it. Ableton is 32bit float which means you can simply turn down the whole mix or just the tiny clipped parts. It will not be clipped anymore.
Or you can be unlucky and have clipped into "analog fx". You will have to declip or copy paste/remake fx.
For the future you can also put a limiter after the fx so that it won't clip as hard or simply record a lot quieter and after turn it up manually
