There is another way to figure out what to craft to increase your level. If the item is gray you will not gain any increase. It should be green for it to increase.
Yeah, I figured this out after a bit. I was also stuck on the same level because I forgot you could go to the trainer and buy new schematics. Now I'm past level 200. It was my first character and I've only been playing the game over a month, that's my excuse.
