AI does seem to have the same glitch were they go too fast when you fast forward in quali or the race gets simulated because of a retirement. In quali if you don't want to spend too much time, do like me. Fast forward till the first AI car is about to start his flying lap, then you live the garage by yourself and do the outlap, flying lap and inlap (never pick return to garage if there is any AI doing a flying lap). After every AI has finished their laps you can fast forward again till you leave again at the end of the session. This works with me and saves some time to.
