Importing cypherl with relationships deltes all nodes in Memgraph

Question

Following advice from How to avoid "request entity too large" error? I've created two .cypherl files. One for nodes and one for relationships.

I've imported the nodes but when I import relationships I lose all my nodes and I see zero relationships but the query execution was ok.

This is sample of my relationships
