What do the grey and highlighted devices when viewing anti theft mean

Hello Andy.
We'd be glad to check and assist you.
Could you share a screenshot (https://bit.ly/3hmUdkG) of the devices screen you are looking at?

I have 3 devices protected by AVG and while setting up device 3 I noticed that 2 devices are shown grey and one is in bold.
Does anyone know what this means. It doesn't seem possible to change which device is highlighted and all three are contactable  via the online site.
I guess it is not too important as all 3 funvtion ok but I am curious
