You're iterating through the same value in inner and outer loop.
Don't do that. It's hard to predict the behavior of such a code.

Regarding break statement, it breaks only the inner loop
and returns to the outer loop/block.

It would be great if you could reduce your code to a short piece
that illustrates your problem and that we could all run.
