Force 200 disconnection after delete SSID

Hello guys!! has anyone face similar issue: one AP disconnected from the SM after power outage, the AP goes to default configuration as SM (IP, device name, SSID deleted), I have replicated the scenarion deleting the SSID (link Up with the SM OK) and trying to saving the configuration then rebooting and same behaviour occured. both devices are running the last SW version. I am wondering if the only workaround is disabling the Reset Via Power Sequence or configure an energy backup xD
