When I submit the form the value selected is not saved, the form presents the field as blank, but if I edit the encounter and modify the value the value is saved.
Since it is concept, drag and drop it under the OBS node. The PATIENT node takes person attribute types.
In the form designer, you will need to delete it both under form fields and from the design surface. Then save.
After modifying the form schema as directed above, you will need to go back to the form designer’s form fields and right click to select Refresh, in order to see the field show up.
Fixed it, the error is caused from the type of concept used to create the coded answers in the question. Where the field is inserted should be irrelevant as that is just a grouping.
