Another "issue" (found in 6.7 and 6.6) and rF2, SessionBestLiveDeltaSeconds when doing offline races do not reset between qualy and race, but it does work correct in online (something is different as my display reset online, not offline when going from qualy to race as I have 2 display options on my screen).
My guess is that the qualy delta session best is still active, but it does reset the sector times as seen here, +1.04 is the DeltaSeconds (I did pause a bit after the sector change):

Again, when doing races online it work as expected but as noted above, when online and going to race the screen gets reset and I have to select next screen (if not on the first), this do not happen offline.

When offline, I have tried below, but nothing happens, should that reset session best?

Edit:
Online rF2, SessionBestLiveDeltaSeconds is reset between qualy and race
Offline rF2 & AC, keeps the Qualy as best, but reset best sector
BestLapTime0 is always reset between qualy/race
