Unit conversions unusable

Some unit conversion rows cannot be used: a row is incomplete, restates a standard metric conversion, or contradicts another row. An imported scenario is refused the same way when the conversions stored with it do not match its own rows. The scenario is not saved, or the run stops.

What to do

Correct or remove the rows the message names in the data Map Units & Conversions reads. For an imported scenario, export it again and import the new file.
