@janbaunooo maybe you still have enabled the standard update line? check if you still have this line:
updates.type=stable
and if so, then put a # as the first char of the line, to comment it out:
#updates.type=stable

By the way, I think the version you have is already the last one, so you won't get any update at this moment anyway.
