Cost prediction

[mabnz]

New user here, I've managed to link the right entities for my Sig Energy inverter correctly in Predbat.

Primarily, in the example below when the battery drops to 4% I would have expected the cost column to indicate import cost since the battery is empty at 10PM. Is this a bug or misconfiguration? The mode I'm using is control charge+discharge in readonly mode. In this mode, should I expect predbat to plan charging prior to a high-cost import period (in my case, 7AM)?

Excerpt from log attached.

Figured it out. Problem was that I had import and export rates entered with the decimal point in the wrong place; it was entered as dollars when it is meant to be entered in cents.
