[PS4] Can't socket small cluster jewels directly into the skill tree

Hi!

I'm guessing it's a bug, so I post it here. As described in the title, I tried to socket the unique small cluster line messenger into the jewel socket above acrobatics. I can slot it in and skill lone messenger too, But there's still the cross as if I had a skill point left over as soon as I'm exiting the menu. As soon as I change maps the inserted skill point will be refunded. The skilled notable won't work. I've tried it with standard white small clusters too, same issue.
