AI Mind Maps result overlap

So, i was trying out mindmap to just check AI applications in different industry. My inputs were-
1.AI in parking management
2. AI in healthcare
3. AI in customer service

As you can see, it didn’t overlap the results instead kept the previous ones as well which takes up quite a bit of space. I feel like it should either generate the results on top of the old one & have an unod button so that if clicked it would revert to the initial results OR it should prompt user to create a new mind map block altogether for new query. Just sayin!
