Guardian Tokens Refunded

I am currently sitting on 5 guardian tokens as when i spend them around 5 minutes later they are all refunded to me from the tree i put them in?

Pls help

Same here. Im only sotting on 2 and it also appears im not gaining exp. It still “adds” it to my bar but it stays the same. I dont want to play anymore of the game if im not being given levels or anything for it .
