Geodata basemaps not matching with external .shp files in the same coordinate system

Describe the bug

Geodata basemaps appear to be distorted, so that external .shp files in the same coordinate system do not overlap correctly.

How to Reproduce

Here is a map of cologne in QGIS, where as an example I traced a reference curve along the bridges. Coordinate system is EPSG:25832 (ETRS89, UTM zone 32N).

When I use Blendergis to zoom into the same area, convert to the same coordinate system and then import the shapefile of my traced polyline in that coordinate, it obviously does not align with the river:

I tried to follow the documentation as close as possible, but unless I'm missing a vital step it appears that the imported maps have a significant deviation in coordinates, even though they display correctly in QGIS with the same coordinate setting. :(

Error message

There is no error message.
