Update Post Meta - Add to Array not formated properly

Hi there,
This feature used to add the user’s id (in my set up) like this: [“2”,“8”]
Right now it’s adding user id’s like this to that same field: [“2”,“8”]1
Nothing in the set up has changed, I tried changing the form to the nestables but this doesn’t work.

@Daniele this too, unfortunately my like system is broken because of this.
