I cannot reproduce this.
As you should have learned by now, we can only make any progress
understanding problems like this if you provide at least some _minimial_
information, such as the version of graph-tool that is being used, as
well as a complete example that shows the problem (in this case, we need
the actual network used.)

Did you read the documentation?
If you want to use the layered model, you have to supply the edge
covariates, i.e.
state = gt.minimize_blockmodel_dl(g, deg_corr=deg_corr,
overlap=overlap,
layers=True,
state_args=dict(ec=eprop))
