The scales do not match.

Lengths and distances do not match when loading maps and OSM data. Example: the distance in Blender is 64.84 m, if measured on a map or with a laser rangefinder - the real distance is 45 m

I'm having a similar problem. The geometry is significantly larger than it should be.
