Is there a way to deflate belly?

dozerlord

This is my first week with the program and I'm loving it. I have been working on a seen playing around with the belly inflation slider having it increase with different snapshots, but when the scene starts over the slider does not return to my beginning position (0) instead staying at the max position (1) from the last snapshot of the scene. Is there any way to make the slider return to 0 from 1 in my first snapshot?
