Minimal reproduce step

Setting snapshot.num-retained.min=0 in table property will cause all snapshots being expired after the maximum retain time of completed snapshots.

What doesn't meet your expectations?

snapshot.num-retained.min should be greater than or equal to 1, so that we always has at least 1 snapshot.

Anything else?
