List	Version	Source flow	Name there	Why this flow
EF	3.1	bfc8ec24-8928-4929-be87-4f05294a48ed	Krypton-85m	The consensus list is built from this one, so this row is the flow itself rather than something matched to it.
ecoinvent	3.8	3a426398-ce2c-4803-aabf-d00b8bc1c277	Krypton-85m	The CAS numbers are the same (378253-15-7); both name the same compartment.

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
