The delete checkbox is present only when there is no validator or the
validator is IS_EMPTY_OR (otherwise, it assumes a file is required and you
are therefore not allowed to delete it). This was actually reported as a
bug a while back, but perhaps not fixed (not sure what version you are
using).
Anyway, why don't you put all of your validators inside IS_EMPTY_OR?
Otherwise, if someone leaves it empty, the IS_LENGTH validator will still
fail.
