I am using the Load Table option to create my knowledge graph, had no problem until importing a table that contains relationships between the same entities.
E.g. Stakeholder 1 is related to Stakeholder 2. Both are the same Entity Type 'Person'.
My table looks like:
Stakeholder_ID, RelatedTo_ID, Relationship_Title
1, 10, Manager
Screenshots of what I attempted in Load Table:


I checked 'Merge' because I already have stakeholders loaded. What ended up after running the load table action is that many Stakeholder entities were created with null Stakeholder_ID, and some relationships have null as the origin or destination.
