Possible monthly count bug

First of all I want to say a big Thank You for this app. It's cross platform and shows a lot of diagrams and data that I want to see in habit tracker. None of the other apps do it so good as Hello Habit. :)

I've recently spotted a minor bug in counting of data.

I have a habit of type "Count", which I check daily (1 daily repetition). I checked the habit 30 times in January. I skipped only one day (January 24th). When I switch to Stats tab > Year and hover on January Bar it says that I've checked the habit 29 times. I think it should be 30
