Rock collectionsFollow

I have trouble with the four rock collections.(Burning, Bubbling, Steaming, Glowing). Whenever I find one of these rocks during my adventures, I cannot add them to my collection. I always get a message that I have either already collected this rock or I have not started this collection. Since I know I have not already added this rock to my collection, I must not have started this collection. However, I cannot figure out how to start the collection and would appreciate some help.

Thank you

Thank you, that solved my problem.
