Osmarender renders locks sometimes in the wrong direction

I’ve entered several lock on Canal de la Marne au Rhin but some are rendered into the wrong direction according to the water flow.

Right: http://www.openstreetmap.org/?lat=48.68998&lon=6.71054&zoom=17&layers=O
Wrong: http://www.openstreetmap.org/?lat=48.69369&lon=6.74645&zoom=17&layers=O

What have I done wrong?

BTW is it possible to set Osmarender as the default render?

I can’t see any reason unless it just needs time to be re-rendered.

There’s definitely wrong rendered in Osmarender, see this sample:

4 times a lock, each rendered differently, just one correct.
