JSON in an Item view of applet adds an extra number field.

1. Ensure that the Field Service Mobile Application is active.
2. Open Studio with Field Service Mobile Application.
3. Find the Work Order Task Applet and open it.
4. Within the field configuration, try to remove some fields and add some other fields.
5. Go to the item view of this record.
See the Item view JSON:
/nav_to.do?uri=sys_sg_item_view.do?sys_id=d6a30173e7b0230003cd6188d2f6a9ba
There are two number fields and also in the dependency fields, instead of only showing what is configured.

This problem has been fixed. There is no workaround available. If you are able to upgrade, review the Fixed In section to determine the latest version with a permanent fix your instance can be upgraded to.
