SQLLineage

[saragaha]

I had a question regarding the SQLLineage library. I namely get that some columns do not have their respective table name and also regarding the lineage of some more difficult SQL scripts. I namely get this as an output, while it should have a table name

The output column of the lineage is the blue column and the orange ones are the corresponding input columns.
So how can I fix this issue and resolve the error? Because it works for most of the SQL scripts, but the reason for this error is unknown.

I also get a lot of in both the input and output columns, but I do not know why this errors is present?
