Can't select field for Default Value field of "Create New Row(s)" action within "Action Sequence"

Thank you for the screenshot. Can you reproduce this issue after re-opening the page in the composer?

Looks like it was possible before to select “RecordTypeID” as field. I can reproduce the scenario shown in the screenshot if I do the following:

1. create a new action sequence
2. add the action “Create new row(s)”
3. select an existing model (which is listed in “Models” on the left below “Components”)
4. add a default value, all model fields are available
5. go to tab “Inputs” and create a new input with type = model
6. go back to tab “Actions” and to action type “Create new row(s)”
7. change “Model” from existing model to the new model (input) that I created in step 5
8. add a default value and try to select a field

Now there are no fields available because the input model has no fields, yet. You should see fields if you go to “Inputs” of your action sequence and add input fields for your input model. If you did the latter and still see no fields, please let me know which version you are currently using. Could you please also share a screenshot of the “Inputs” tab?
