When I tried to export to epanet without first having any source (i.e., reservoir) I got the same message. But the issue was solved after having the reservoir. May be your section does not have any source.

Hello. I solved the issue.

The software cancel demand for all node that are not connect to the network. I when I fix that problem, every thing is OK. Thanks very much.

Indeed, QGISRed detects network nodes with assigned demand but which are isolated from any supply source or reservoir. In such a case, when exporting the model to EPANET these demands are automatically cancelled to avoid errors when running the model.
