(JSPUI) controlled vocabulary not showing

[kpet]

Hello,

I have a DSpace 6.3 installed on a linux machine, using tomcat 9, jre 1.8, ant 1.10 and maven 3.3.9.

I am trying to use controlled vocabularies, I have followed the documentation and in XMLUI, the vocabularies work as expected (the add-on appears next to the input field).

However, in JSPUI, there is nothing rendered next to the input field, so I cannot actually set a value from the vocabulary.

Any help in this will be greatly appreciated.
