Wrong tilerow when download with boundingbox

[CaptainInler]

I'm downloading this tile to a MBTiles:
http://tile.thunderforest.com/cycle/4/8/5.png
So the image has this Parameter:
zoomlevel: 4
tilecolumn: 8
tilerow: 5

I have following code:

from landez import MBTilesBuilder
mb = MBTilesBuilder(tiles_url="http://tile.thunderforest.com/cycle/{z}/{x}/{y}.png",filepath="C:\\Temp\\test.mbtiles")
mb.add_coverage(bbox=(8.0, 47.0, 8.1, 47.1), zoomlevels=[4])
mb.run()

When I extract the tile out of the MBTiles, I get the correct Image but the wrong filename; 10.png instead of 5.png

By examining the mbtiles file I see following
zoomlevel: 4
tilecolumn: 8
tilerow: 10

Why did the tilerow messed up? I have even tried using cache_scheme="wmts" but this did not change anything.

Any Idea how to get this fixed?

4/8/10 is the Google naming scheme for 4/8/5 that other schemes (notably OSM) use.

You can see this in action here (the map shows both IDs): https://www.maptiler.com/google-maps-coordinates-tile-bounds-projection/#4/-4.76/48.49
