Extend inop after 1st stage activates

As the first stage passes the proximity switch at the bottom of the mast assembly the extend function becomes inop. Extend works fine as the carriage is in the first stage. Cluster reads extend. Hoses pressurize for retract and extend. Battery water level is good. Battery voltage is good at 24v. Not sure if it's a signal issue. Proximity switch was replaced and lost all functions. Reinstalled previous switch and back to square one all functions work except for extend after first stage leaves. Any information would be appreciated. Thanks so much.
update: mast harness fixed the issue. thanks so much.

check your mast wire harness that goes out to the control manifold on the carriage. That manifold controls the functions of the carriage and extend operation. The fact it operates in one position but stops when the carriage is raised past a certain point is a sign that the mast cable may have a broken wire in it.
