After installing the app, after a few days I get an 'undefined' in the first row of the card 'bottles by producer'. see screenshot.

Hi, I have a similar problem (for appelations and vintage). Did you by any chance figure out a solution?

If anyone else encounters de same problem: in my case it was due to the fact that I had consumed the last bottle from specific Appellation. The sensor was not automatially cleaned up but it could not find any bottles anymore. The solution was do delete de sensor by hand.
