I'm  a beginner  in OpenLCA, i have been using free databases like European reference Life Cycle Database(ELCD) and The Environmental Footprint(EF), I have copies some of the process from EF and ECLD for my own use but the flows used on ECLD and EF are different, so while calculating in product system, the output shows two duplicate category with unique UUID. does anyone have any tips to resolve this?

Thank you

These both databases are meant to be used in isolation, and should not be combined.
