Note 3 installed Lollipop device status custom?

I installed Lollipop UK o2 version on my note 3 using odin. Now my device status says it's "custom" rather than "official" is this normal? It's also lagging a good bit....

Never mind. I did a factory reset and it now says official. Guess that was the fix and still on Lollipop
