warning messages in Lavaan

[Jassmyn]

I got the following warning message in my Modell 1:
Warning message:
In lav_data_full(data = data, group = group, cluster = cluster,  :
  lavaan WARNING: some observed variances are (at least) a factor 1000 times larger than others; use varTable(fit) to investigate

I am totally new with R, so I have no Plan how to fix it.
Does anyone have a suggestion?

In my Modell 2 I got ecen more Warnings:

Warning messages:
1: In lav_data_full(data = data, group = group, cluster = cluster,  :
  lavaan WARNING: some observed variances are (at least) a factor 1000 times larger than others; use varTable(fit) to investigate
2: In lav_model_vcov(lavmodel = lavmodel2, lavsamplestats = lavsamplestats,  :
  lavaan WARNING:
    The variance-covariance matrix of the estimated parameters (vcov)
    does not appear to be positive definite! The smallest eigenvalue
    (= -7.794870e-02) is smaller than zero. This may be a symptom that
    the model is not identified.

I would appreciate some help :)

You can plug that warning into the search bar to find many previous posts already addressing this FAQ.
