Quick stats question

[WalkAmongUs]

over my last 20,000 hands my stats look like this:

VPIP: 22.2
PFR: 15.25
W$WSF: 44.15
WtSD: 39.96
W$atSD: 44.75
AF: 2.05

MY W$SF looks high (as is my WtSD) and W$atSD looks low. I'm assuming this means I'm taking down an above average amount of pots without a SD, but when I make it to SD its with losing hands.

Any thoughts on what is causing this? Am I letting second best hands off the hook too much? It almost feels as if I'm playing in a way that lets people fold too often when they're beat.
