This is not a Runalyze bug, but probably a translation error in the map used to generate an Image.
Steps to reproduce:
Select an activity at or near Roode Polder 15, Oud Ade, the Netherlands
https://maps.app.goo.gl/CmRsE3or17yNZB3T7
Use the "share" icon and then "image"
For some of the map scales, the street name Roode Polder (Red Polder) shows up as a street name starting with: "Россия"
