Static Tiles of custom map styles have display issues

[uubbbb]

I created a new streets-v12 style map in Mapbox Studio without making any changes, but when I use Static Tiles, a lot of ✖️ appear after zooming in. I don’t know why. Demo address: https://jsfiddle.net/nme03p7y/

But using streets-v12 directly does not have this problem. Demo: https://jsfiddle.net/s3hzbu2y/. I created a completely new map without making any changes.
