Is this a bug?

He didn't buy anything in this floor, however he did do some "ghosting".

Now look at the score on the left and the one on the right. Left one shows 75150 / 238650. Right one, however, shows 105150 for the level (not 75150). I believe it didn't count the "ghosted" diamond gems properly and instead counted them as regular gems. Is this normal or is that a bug?

And for the people who don't know what "ghosting" is: it's when the ghost spawns at 2:30 and touches the regular gems (emeralds, rubies and sapphires) turning them into diamonds in the process.

seems pretty buggy to me...
