Gemling Legionnaire bug

Currently running the node tree to gain 3 additional skill slots. I respecced into to these after choosing different initially. I was initially able to add things to my additional 3 slots. I noticed that the skill gems were not working, so I removed them. The additional slots then disappeared, so now I am back to the original 10 slots. Not sure what to do top get them back!

+1 same issue here....

would be great if the basic class design would work.
