Removing them means that you get the default values. From the man page:

    max-lease-owner-ship defaults to 10, and max-lease-misbalance
    defaults to 15

In other words, by configuring them to 1 and 2 you have values which
are significantly lower than the defaults. This may be the source of
your problems.
