As a new wazer, I encountered some weird routing options for my daily commute. I traced it down to some redundant/badly connected segments on the Keerensheide junction in the A2 highway, near Geleen in the Netherlands.
Please unlock/fix the sections shown:

This construction was designed to prevent routing along the parallel lane when you do not have to change to the A76. I do see a problem though, the short stub that has been added to force a keep right for the cloaver leaf was two way, which may have caused a route onto the stub and back.
You will find this construction, or one like it, on most of the cloaver leaf junctions with parallel lanes in NL.

After a map report, the problem has been resolved by fvwazing, thanks
