We have only two course formats set: tiles and multitopic.
I have been adding new content in the Tiles course and noticed that each new item was creating a new topic. This was annoying (since I was creating the content in existing topics) but was easily solved by moving the item and deleting the false 'tile'.
However, now I am finding I create a single item and I am faced with the format creating hundreds of new topics; and I mean hundreds.
I created two books and found I had 1487 topics! I started with 4.
a) how to get rid of so many topics
b) what the hell is happening?
