my guess is that two layers are disjoint and are not connected by
the primitive coordinates generated by the DLC procedure. You need
to connect two sheets using nonvdw array as suggested by Pavel.
I'd suggest to add several "bonds" between sheets. Most likely this
will solve the problem.

Kind regards,
Alex Granovsky
