Something weird is going on with my self-hosted instance.

[orangecoloured]

Several weeks ago I noticed that my website stats became empty and all the values were "-100%".
I did not look into that, because it's my personal website and usually I don't get a lot of visitors.
But the stats persisted like this for some time and today I decided to do something.

I have my instance hosted on netlify, so I cleaned the cache and rebuilt it.
And now I have this.

• no data but today for the past 12 months
• the countries list shows something weird

What's happening? My fork is synced with the main branch of the main repo.
