L6470 ext switch-SW-erratic behavior

The releaseSW command is behaving erratically.

We have our own PCB based on ST design. On Power up GoUntil is executed. Limit Switch used is Omron EE-SX951-W.

GoUntil never fails and SW input is detected correctly all the time.
After GoUntil, ReleaseSW and Move are executed. Sometimes (unpredictably) ReleaseSW and Move are not executed.

Appreciate inputs for trouble-shooting this behavior.
