Well, let's see - we have z scores, bootstrapped CIs, Wald test (Model Test), and loglikelihood difference (chi-square) testing.
I would not necessarily fix an insignificant parameter, but report it as such. Perhaps the sample size is not sufficient, which sometimes happens on level 2. But sometimes the data doesn't carry enough information about a parameter in the specified model.
