Sorry, my English is bad.
When I put 14 on black, filled it, and change colour to something else, when I click the black with the colour picker, it said 13.
When I pick one colour filled with bucket or paint with, it bleeds to another colour.
For example, when you have 5 bottles of beer and you drink one, It's 4.
Can someone please help me how to fix this? It's annoying now.
