level 10 rank chocobo barding

When you raise one of the chocobo talent tree to rank 10 you get a special barding for your chocobo. with the reset of chocobo skill and extra point for leveling a chocobo beyond rank 10, it is now possible to get to rank 10 in more than one tree. The problem is you only get the first barding you hit rank 10 with and it do nothing if you raise your chocobo to rank 10 in an other tree after. is it possible to switch those barding reward into achievement for getting a rank 10 tank/dps/healer chocobo so you can get all 3 of them eventually ?

This isn't a bug, it's just the way it works. With the increase to chocobo ranks (through Thavnarian Onion), it's possible to fill out all three trees, and thus get all three bardings. You get your second barding when you fill out a second tree (I think that happens at rank 16 or 17), and your third when you fill out the final tree at rank 20.
