Gas Cubby 2.7 broke all history data collected for several years

[ababak]

All data earlier than May 2014 got screwed up. It looks like total cost was left intact while cost/litre and litres are invalid (cost became smaller while litres count proportionally increased). All this resulted in incorrectly high L/100km data. I've seen another report about incorrect gas consumption values in this forum.

Fortunately I've got a CSV data exported on 18th of September, 2014 with correct values but currently the synced data is broken for me.
