Not able to load params in MP

Ground Control Software Mission Planner
1

In MP 1.2.99 > config > full param list and using the drop down list on the right hand side of the screen:
Selecting 3DR_rover, beginner, intermediate, or advanced and then clicking the load params button, I get nothing but a blank screen. Other selections do show some params.

I uninstalled and re-installed MP and got same results.

Any help would be appreciated.

if you select an option, and no params are required to change then it would be blank.
