monitor levels changing while in low latencey monitor mode Pro Tools LE

[turk sanchez]

when I am doing vocal punch ins using low latencey monitor mode the pre-recorded audio is much louder than the audio being recorded...to put this another way the vocals are set at a good level and when I punch in they are much lower (on the same track). All the levels are the same on the track in the end...the track is consistent...this just happens while recording punch ins in LLM mode...and not just vocals of course...anything you overdub/punch in.

Any idea why and how to fix it?

Thanks guys.
