Bugs with streaks

[Ezelty]

I've observed some bugs concerning the streaks. They only happen with the tasks I've had since January, not with the ones I've created in order to reproduce the bugs.
Some things I've observed:

• "longest break" seems to be always 1 day more than the actual longest break (it is at 1 if there has been no break)
• the streaks on the graph don't always correspond to the actual streaks
• sometimes the last day ticked is not counted in the streak: for example, I have a 3 days streak, then I tick the item, but still have a 3 days streak.
• I've unticked some days of my different series, then re-ticked them: the count has changed (for some series it went bigger, for some others smaller). In fact, it seems that some days were not taken into account for the streak until I unticked and re-ticked them.

I really don't understand this bug, but maybe you'll be able to know why the things I have noticed happen.

Strange! Are these multi-tick or normal tracks?

So the bug only happens with older tracks. That is at least something that I can use to identify the bug.

[Ezelty]

Both multi and normal.
And it only happens with older tracks, but I don't know how old they have to be.
