Profession - Legendary Crafting - Level 4 learned and can't create item

Character name: Hellsfury
Bug description: I have all 4 levels learned for Umbrahide leggins but it doesn't allow me to create anymore any item of that type greater than the first level (190). I have materials and everything but the button to create the item is grey out and on the bottom there is a message "Profession Trainer : Shadowlands Leatherworking (100) Cost 25 gold" As if I don't have leatherworking learned or level 100 but it is. This message disappears if I select other recipe or Rank 1 for this item. I have to mentioned that in the past I have unlearned Leatherworking and now I learned it again, level it again until level max(100). All 4 levels appeared again but I can't select higher ranks, only rank 1. Let me know if something can be done. Thank you, Adrian

I'll make leatherworking on another character and unlearned it form Hellsfury. You can investigate for future cases but I'm not waiting for a reply anymore.
