Tournament stats bug

I've joined more than 20 tournaments but my stats of tournaments show that I've played in only 5 if you check the medals or trophy I got you'll see it's more than 10 and still it only shows 5 .

Are you talking about live tournaments?

Both

Only Daily shows there right now.

Live are under Play > Tournaments

I didn't understand what you meant maybe you are talking about tournament page but I'm talking about tournament in "stats"

The tournament section in stats refers to daily tournaments 

But till now I only participated in two daily tournament so how does it show 5 and btw those tournaments aren't over yet

That's exactly what I'm talking about. The Stats page only shows Daily tournaments right now.

It shows 5 games and 2 tournaments. The games count doesn't match your games played in those, but I don't know how often that updates, but the count may be bugged.
