Dear Chihiros! I use your application for my B120 lamp, but I also use the other maintenance note-taking functions and I really like it! There is a bug now! Whatever I enter, for example a water change, it resets the filter maintenance counter! However, it would be important for me to see when it was cleaned! But it doesn't just do this for water changes, it resets whatever I enter! Even if I don't modify it! Please help me solve this! The application is updated, I exited, went back, deleted it! Thank you in advance for your help! Best regards! Tamás Szabó
