"Reorder Field" missing in Pods 2.7

[zscheatham]

I'm running WP 4.9.1 and just upgraded to Pods 2.7. I created a new ACT and in the Admin UI tab, when checking "Reorder" under the Actions Available section, I get no option to declare the Reorder Field. When I revert to 2.6.11, clicking "Reorder" displays the option to set the "Reorder Field" so that I can create a field to key off of.

*NOTE - it doesn't seem to be breaking existing ACT pods. If I had previously created a field to use as the reorder field I am still able to reorder those pods. It just looks like the UI element to set that field is no longer being revealed when checking "Reorder"

Update -- upon further inspection, that "Reorder Field" is present, just set to display:none; and it looks like the trigger is the problem... clicking Reorder is not updating the display of that field to allow me to input it.

Also, it looks like if I do add a new field and give it the label "menu_order", reordering works on the new Pod.
