[SOLVED] Ghost device which consumes credits

Hi All,
I have one device only collecting data from 4 sensors. Everything works great, however…
When I check credits -> usage I see that credits are consumed by 2 devices (!?)
To leave no shade of doubt, in “my devices” tab, I have 1 device only.
Could anyone explain? How to remove this ghost device?

Greetings, your device has 15 variables,your first free device can have as many as 10 free variables. After the tenth, every 10 additional variables into your device will result in a deduction of 500 credits per month from your account.

All the best
