Calibration tab in axis GUI

A while ago I upgraded from 2.4 to the present release of 2.6. When I open up calibration tab( for pid tuning) , the box opens but there are no fields , big gray box with apply and quit on the bottom. Any ideas what might cause this?

What does your ini file look like? The settings that are inserted into the tuning menu are pulled from the ini file.

Sidenote: that menu is for servo calibration, for steppers i do not know if it does anything.

It took me a while to get back to this. Attached are the .ini and hal files. Im having the same issue on another machine with
ver 2.5.1. Both machines initially started with with imported hal/ini files from ver 2.4.3. Thanks as always
