Device Notification not working anymore VeraLite UI5

Hello

i just purchased VeraLite and managed to register lamp modules, PIR and others succesfully.
I also managed to get device notification to work, but after one day it is not working anymore.

When i go to settings on any device, like a lampunit (everspring) and then go to the notification section, i see the text string “Undefined” under the notification name entry field.
When I add the notificaiton (as i used to do before) it now does not result in a proper notification but instead it looks that it does not save. eventhough i click the Add and Save field.

I can get it to work in a different way by connecting notification to a scene, but I would like to do this directly to the device.
This is also a new feature in UI5 as I understood but not working for me

any thoughts?

I managed to get rid of this error by excluding the unit and including it, but this will hopefully not occur more times, as i have to exclude and include all the devices.

I don’t know what caused it
