Dezzy, this is not Botang's hole. The hole you have fixed is positioned too high to actually leak.

Botang's hole is hiding below cracked mastic and leaking through cracked mastic, so you won't see it in the way you see it in first picture, because you need to scratch mastic a bit first, which will fall off and reveal Botang's hole. Only then you will see a picture similar to 1st picture in your list.
