Okay, so this is very interesting. I've been playing around with the "Close by" widget, showing nearby gas stations and their prices. I noticed that when opening the settings for this widget by tapping the three-dot icon I could select 'Ethanol' as the gas price and 'E10' as the gas type. After settings those preferences the widget shows the prices for the 'E10' fuel.

When opening the settings menu for the second time it's missing all but one (E85) option from the list. After restarting the app all options including E10 are back.

Overall the behavior is inconsistent, so I wonder why this is happening. Is the app fetching fuel types from the server in the background or why does the list change randomly?

For now I can say that the list stays populated with all fuel types, so the bug has either been fixed server-side or somehow resolved it self.
