Duplicate Custom Fields and Segments Created

I initially tested this on a staging site with my list.

I then later activated it on a live site with the same list. After selecting my list in the WordPress it created duplicate WooCommerce custom field and segments in Campaign Monitor with a “1” suffix.

It was not clear wether new data would be stored in the original fields or the duplicate fields.

My expectation would be that if a WooCommerce Field or Segment already exists in Campaign Monitor it should use the existing Fields rather than creating duplicates.
