I have managed to hide the fields of the social networks that do not interest me at the profile member, and I have been able to change the Google+ icon to the Instagram icon thanks to another topic on this forum.
Now I need to change the title of the field that still appears wrong, like google + for Instagram, you can see it in the attached file.
We've already removed some of them and added a new social network in the next wpForo version. It'll be released within next 1-2 weeks.
