I found a connectivity issue on the A57 around Worksop, which I think I've fixed. I don't know if this will correct your route or not though. I'll check it again in a couple weeks when the changes have gone live.
Waze shows two routes on the website: http://world.waze.com/livemap/?zoom=4&l ... &to_seg=-1
The purple route down the M1 comes off at J26 onto the A610, with a estimated time of 1 hour 4 minutes; potentially faster than the route you took. Meanwhile, the blue route avoids going anywhere near the A57 and Worksop, yet the return journey is correct.
It could be that Waze routed you the longer way to avoid some traffic congestion, or some roads that it knows to be slow at certain times of the day.
