Ok, fine, you don't have any customization. Which means, you should use the latest FSDT AFCAD, which should be updated, and you surely won't have any issues with jetways, which can only caused by the wrong customization used or the wrong AFCAD used.
Note that, nothing in this update has updated any files at KLAX since the last update in early July. Which means, if the updater made a backup now, that you modified the FSDT AFCAD OR you skipped the previous update.
