Yes, it is supposed to be an actual "common currency", which binds each
of the "Split Values". The transaction does its double-entry balancing
using the Split Value in the transaction currency. The exchange-rate
dialog also uses the transaction currency to map from the "Split Amount"
(which is denoted in the Split Account's Commodity) to the Split Value.

This is a bug. How were these transactions created? You should never
have a transaction with a non-currency "common currency".

Indeed. How were these transactions created?
