List Version Source flow Name there Why this flow
ecoinvent 3.12 954f7083-c85d-428f-af32-177be2e25ac9 Technetium-99m A curator's mapping table names this substance, which had no flow in this compartment, so this flow was created for the row.
ecoinvent 3.8 954f7083-c85d-428f-af32-177be2e25ac9 Technetium-99m A curator's mapping table names this flow.

Something wrong here?

A flow can be wrong in three ways, and they are decided differently. Pick the one that matches what you are looking at.

You do not need to run a build or clone anything. Name the row and say what your evidence is; the measurement is done for you. How contributing works
