Unable to create notes in Employee Profile using PUT EMPLOYEE

Hi, I am unable to use PUT EMPLOYEE to post notes to a staff's profile in the child account (parameter name: notes). Whilst the information is successfully uploaded and can be retrieved via GET EMPLOYEE I am not able to see it in the staff's profile page.

The JSON submitted to the API is as follows:
"id":"5920741","status":"-1","notes":"BC disable"

The aim is to disable an account and leave a note in the process. Appreciate the help, cheers!
