Hitting hard stop during a zero return

$

Horizontal Kitamurra machine. When I zero return the "Y" axis, the machine will decel when the first dog hits the limit switch. Then the machine will continue slow but never homes out. The machine will continue until it hits the hard stop. I checked the limit switch with an ohm meter and it does change state when the plungers are pushed in. I also watch the diagnostic bit change so I believe the limit switch is working. Need help.
