Coordinates and biome display not working after making new default world.

[OPRESEK]

Hi, I recently deleted my old world for a server and generated a new one using Chunky, everething is fine except the Y coordinates (it displays ??? or random numbers, depending on where the cursor is on the screen), and displaying biome when hovering a mouse over the webmap. When I made the new world, i deleted all website files, for them to generator on new server start. Everything worked fine before creating the new world.

The server is running on 1.20.1 Paper and website on Nginx on the same machine with Ubuntu 20.04.6 LTS.
