Yes, I did select the "yes" option for AFCADS on both occasions.
Then the problem shouldn't happen, or there's another AFCAD used by the sim, not the FSDT one. Maybe some AFCAD you modified trying to fix the issue yourself ? Or, maybe there's something wrong with the download.
Check the file date of the sceneries AFCADs: CYVR, KDFW and KLAX should all have their dates August 10th 2016. If they aren't, reinstall the Addon Manager and be absolutely sure you reply YES to the question about downloading the AFCADs.
