TED policy report is empty

I evaluated a trained model using

rasa test core --model ".\models\data_all.tar.gz" --stories ".\data\all" --out ".\results\data_all"

which produces the failed stories report, story confusion matrix, story report and TEDPolicy confusion matrix and report but both TEDPolicy files are empty (png that shows confusion matrix without data and empty json).

The config uses TED and Rule Policy only.

Console output:
