Custom actions: unable to edit or reorder actions after adding a new one

[jcross2562]

Describe the bug
I was attempting to add a new custom action to the list and then reorder the list so that things appear logically. Adding a new action worked fine, but it does not appear to be possible to reorder the list.

To Reproduce
Steps to reproduce the behavior:

1. Go to Application Settings --> Custom Actions Checklist
2. Click on Add Custom Action
3. Enter the data and click Create
4. Drag the newly created item up to where you want to place it in the list
5. See error (DESTINATION IS OUT OF RANGE)

Expected behavior
The newly created action can be moved to its new position in the list (by dragging and dropping it), and the list then accepts the change with the items numbered with new order.

Screenshots
Here is a WEBM file that demonstrates the actions that I took to attempt this change.

In addition, here is how I would prefer the list to appear if the reordering had been successful.

Additional context
A few more notes that probably would be important to mention:

1. When I attempted this yesterday, the current list displayed with every beginning number ending in "0". After the attempt to reorder the list failed, I deleted the newly created item by dragging it over to the trash can area. After it was removed, all items in the list (after the 1st 2 items) were renumbered so that the initial number ends in "9". This also appears to be a weird display issue/problem.

2. When adding a new action, there appears to be a character limit in the Custom Action Label field, as you can see in the WEBM file. When the text exceeds the limit, the field is bordered in red and the Create button is grayed out. If the limit exists, it probably would be good to specify what that limit is. (Although, it's apparent that there wasn't a limit in earlier versions since several of the existing actions in UTSW's list clearly would not fit.)

3. After the new item is in the list, the ability to edit existing items also fails. Clicking on an existing item pulls up the modal with no text in the label field. (Items that are numbered before the new item can be edited.)
