Can someone explain to me why the donation numbers go down at the exchange race? (https://hodler95.github.io/exchangesrace/) I've been checking this 5 times a day and I see the total amount of donated BTC go down after a few hours. Are these funds being used for other purposes?

Edit* False alarm... It looks like keeping a tab open in my browser and refreshing it is bringing up previous data. I cleared cache and revisited the page and the numbers were back up.
