Multi-Button Text via OSC Message

Have a six button Multi-button element, /selFactorsHF and a label /SelFactorsText

Using multi-button address: /selFactorsHF/4/OSCpilot/Text
I am having trouble getting anything other than numbers to display on the OSCPilot UI in the text field. The label works fine.

Works:
ADDRESS(/selFactorsHF/1/OSCpilot/Text) INT32(6) >> Displays 6.0 on first button
ADDRESS(/selFactorsHF/3/OSCpilot/Text) FLOAT(9) >> Displays 9.0 on third button
ADDRESS(/SelFactorsText) STRING(Jump0) >> (a label, displays Jump0)

Doesn’t work:
ADDRESS(/selFactorsHF/2/OSCpilot/Text) STRING(new_Text) >> nothing changes on button 2
ADDRESS(/selFactorsHF/4/OSCpilot/Text) STRING(Trippy) >> nothing changes on button 4

Below is the logged packet traffic.
