is driver error ON in QLFY?

After the last update I noticed some "big" gaps in the times of the drivers during qualifying, even after comparing the cars with other managers I don't understand that difference.

The same now also happens in my two car league where before the update the drivers were doing the same times (both drivers are similar). 

The thing is that it doesn't happens every race so my guess is that driver errors was enabled during the last update, is that intended or true?

This is a big issue and ruins races for some before they have even started. Qualifying issues aren’t improving they are getting worse.  Weird things are happening.  For example, cars qualifying last make up 7 or 8 positions in first half of opening lap while,other cars lose a similar amount of places and within another lap it’s reversed again.  It’s almost like the algorithm is struggling to work out true position of cars.  Also it’s getting predictable to work out who will be at back of grid yet they are finishing much further up the field.  This has been a big problem since the last update (Commenting on observations from another of my accounts, with this one it’s harder as they are a number of inactive managers in the league).
