camera Anti-theft alarm goes off

I turned the anti-theft alarm off on one of my cameras to adjust its position ( Homebase 2 - Eufycam 2 ) but when I re-enable the alarm in the app the alarm goes off all the time… If I disable the alarm it stops sounding OK, but I have tried to re-enable it many times and same result, the alarm sounds continuously until I disable it in app. do not dare to re-enable it as it is pretty loud… I have tried restarting the Homebase, and also cancelled all the notifications in the app - Any ideas ?
