Can you share your import statement?

And what your graph should look like.

Data importer doesn't support array properties (yet).

But you can have it generate the cypher-script for you (three-dot-menu-drop-down) and you can adjust it.

Then you can convert columns with the arrays with apoc.convert.fromJsonList into native arrays in cypher and do with them what you want, e.g. UNWIND and find nodes with the values or set them as inidvidual values on nodes or relationships or as vectors.
