*MapJSONArray* output fields deleting values

[ChewinChaz]

In the "Map JSON Array" apex action, the configuration screen is deleting the values from the "Set this output field:" input. There are multiple users experiencing this issue according to the comments on the unofficialSF blog. Weirdly enough, existing flows using this component are working just fine, only new flows are having this issue.

Steps to reproduce:

1. Add the action to the flow and map the ids from the JSON array to the appropriate record fields.
2. Click "Done"
3. Double click the action to bring up the edit screen again. The values in the "Set this output field:" inputs has vanished.
