Firstly, <?= is a bad idea, as it's not very portable and relies on
short tags being on, which causes all sorts of problems should you ever
need PHP to output XML.

The only reason I can see that the div will always appear is a logic
error. Are you sure that the $erros['anexo'] variable is not set at some
point and not just set to an empty string? An empty string is very
different from an unset variable. Try using var_dump($erros['anexo']);
in your code somewhere to see if the it is actually an empty string
