lavaan WARNING: covariance matrix of latent variables but lavInspect( fit, "cov.lv") are all positive,what's the problem?

Adding that your factor correlations are very high across the board. The lowest one I spot is .76.

Please help me. Can I use a vcv matrix of factor scores as input to lavaan?

I have a covariance matrix from factor scores and I want to use that as input for my analysis.
