Steps to reproduce

1. Create a new module with required fields (or use attached module)
2. Open module
3. Click on Add item in sidebar
4. Click save

Expected results

1. On every field which is marked as required, "This field is required" error is expected after clicking Save changes button.
2. Clicking Save changes should only trigger "This field is required" errors and prevent saving the new item

Actual results

1. Only the Name field has "This field is required" error
2. After filling the Name field, clicking Save changes will save the new item.
