I created Nested multifield by using Granite UI framework.
I am using Acs -commons package(acs-aem-commons-ui.content-4.6.0.zip) to store values in JSON format.
Nested multi field level created rich text field, values is not picking correctly in dialog, but when replace text field its working perfect, All values are storing in JSON format.
Multifield level rich text field working fine.

I am not sure if it is a bug from ACS Common. Please check https://github.com/Adobe-Consulting-Services/acs-aem-commons/issues/2251
