Cannot Initialize List Parameter for Procedural Scheduling Goal

[Mythicaeda]

Checked for duplicates

No - I haven't checked

Is this a regression?

No - This is a new bug

Version

develop

Describe the bug

In the event that a procedural scheduling goal has a List parameter with no default value, upon clicking the "Add Value" button to initialize this list causes nothing to happen. Note that the "Add Value" and "Remove Value" buttons work as expected once the list has been initialized (by manually doing so via the API)

Video of the bug (the derivationGroups parameter has been manually initialized in the DB):

Reproduction

1. Unzip and upload the attached procedural scheduling goal to the UI
2. Add an invocation of the goal to a plan
3. Attempt to edit the invocation's arguments on the Plan's page
