I tried all 4 houses and got all 4, and I tried just 3 and 4 and got 3 and 4.
I don't see how you can have lost two houses as there isn't a folder for the default houses that you can delete.
I know this is a dift question but you are putting the arrow icons in aren't you? And the number has to go to the left of the arrow.
I wonder if it's something to do with the custom houses
Patrick would be the best person to tell you what could go wrong.
Edit.
I just tried putting the numbers at the right of the arrows expecting to see nothing but still saw the houses.
