The item on the left is the one im reffering to, it has a black number over it and the number is random, it does not equal the number of items in my inventory. i really have two dirt, but it shows 2 (correctly) then in bigger black(?) text it shows 20. The item on the right shows how It should be.
It looks like this appears on blocks. For example, furnace, dirt, steel blocks, ect.
Any idea what this is and how to fix it?
