It looks like the config file is not delivered completely to the AP. Probably due to MTU issue. The ZD is sending the fragments which is in bigger MTU size than the MTU size set on the switch\network path.
Are there any switches, Firewall in between the ZD and AP? If yes, please check the MTU set on these network devices. Configure the MTU on the ZD lower than the MTU set on the network devices.
Example, if the Switch\Firewall has MTU set for 1300, then set the MTU on the ZD as 1200. Set the MTU on the AP with the below CLI command
