Portable Wifi hotspot using background data

[DatManWolf]

I am at a loss right now.

My wife and I have an LG G4. For some reason her Data Manager shows that the portable wifi hotspot has used 3.5gigs of background data but when I look at the settings for the hotspot everything is off.
What am I missing because this is killing our data. On my G4 I don't have this issue and our settings appear to be identical.

Thats odd. SO you didnt use it at all this month?

No, the settings were all off when I checked her phone after we got the data usage notification text.
