Scaled Chi-Squared Difference Test (method = satorra.2000”)

lavaan NOTE
:
   
The Chisq column contains standard test statistics, not the
    robust test that should be reported per model
. A robust difference
    test
is a function of two standard (not robust) statistics.

The second model is significantly worse, based on this test. Looking at chisq and df, however, one might suspect that both models are misspecified. In this case the test is invalidated. Check the model fit.
