Hello,  
I am having a problem migrating my devices.  
They all switched to ABP without me asking them.But they are still displayed in OTAA. (See picture).

My sensors have “Devices Address”, “Network Session Key”, “App Session Key” and so the migration is not working.

Why did this happen? and how can I proceed to do the migration without changing my sensors?

I hope I have made myself clear.  
Thank you in advance for your answers.
