You are most likely using Open Content in Combination with a Bootstrap 4 Theme.
If that's the case:
- Make sure you are using the latest version of Open Content.
- Go to "Edit Global Settings"
- Uncheck the "Load Bootstrap on Edit Form" setting
- Check the "Load Glyphicons on Edit Form" setting
If you used the Form Builder, Open Content generates a file view.json. This file contains a template for the rendered form and is used to create multi-column layouts. If a view.json exists and you add a field manually to schema.json it will not be rendered in the edit screen if it's not added to view.json.
The solution is to either delete view.json or use the builder to add the field.
