If trading accounts are on then expanded splits show the amount of the split, not the value.  They also show the currency symbol for all splits not in the transaction's currency (i.e., all splits where it matters which is shown).  It's been this way since trading accounts were first implemented, and was discussed then.  Changing it would be easy, but I think would add confusion.  I could easily argue that changing it to always show the amount, with or without trading accounts, would be better.  It really should show both.  

The current situation is not ideal.  When I implemented this, I assumed that the Register2 code would replace the Register code soon and this would all be moot.  That didn't happen and isn't going to happen anytime soon.  Should we add a column to the register to show the amount in expanded splits in non-priced registers?  That might help people understand what's going on.
