List Version Source flow Name there Why this flow
agribalyse 3.2 01965ae2-da81-5cad-a93e-5759cb34ddc1 Technetium-99m The CAS numbers are the same (378784-45-3); both name the same compartment.
bafu 2026-v1 15e1d599-5ff9-5ce5-9d9c-3c047b149526 Technetium-99m This substance answers to the name the row carries; no flow of this substance sat in that compartment, so this one was created for the row.
bafu 2026-v1 8a7cee4c-e5d8-5536-a375-f6328bdf93ae Technetium-99m This substance answers to the name the row carries; both name the same compartment.

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
