Meta Avatars Editor Integration Issue

I am using the last meta avatars sdk (v. 35) and I've added the logic to integrate the meta avatar editor inside a VR application following those rules: https://developers.meta.com/horizon/documentation/unity/meta-avatars-editor-integration .

Although in the linked page the code sample is totally different compared to the actual code in the OpenAvatarEditor.cs, I succeed in integrating the avatar editor, but the editor panel showing up is still the previous avatar editor version (v. 24).

Have anyone had the same issue? 
Thanks for any help!
