Hi everyone,
I'm currently working on importing LVFeeder and MVLVTransformer as Subnetwork Controllers in ArcGIS Pro. The import process works perfectly for LVFeeder, but I'm encountering an error when trying to import MVLVTransformer.

When I manually import the data, there are no issues. However, when I attempt to import it via a CSV file, I receive an error.
Has anyone experienced this issue or have any suggestions for resolving it?
Thank you!
