Puzzles having tactics revealed

I started using the new puzzle feature I it is wonderful but I notice it will tell me "find the mate in 3" on the right I feel this has to be a bug if its telling me the solution to the puzzle is mate in 3 If its intended this way I might suggest that there be an option to hide that information but if this is a bug I wanted to bring it to lishogi's attention.

When the puzzle was added to lishogi’s puzzle database, it was stored as a mate in 3 puzzle and hence is visible that way.
