To confirm the bug:
Add two combos of 99 to a blank matrix and save it as a range.
Add the remaining four combos of 99 in another blank matrix and save it as another range.
Now switch between the two saved ranges and you'll see 99's number of combos in the matrix doesn't change from 2 to 4 and vice versa. I have to toggle off/on the "display # combos" to manually fix it.
