5.1 UI displays in duplicate. LG G4 locked to Sprint, my provider.

AC Question

I have a recycled LG G4 locked to Sprint, my provider. Its running 5.1 but the UI is displayed in a sort of duplicate. Took my LG G4 to Sprint to activate [swap sim] and hadn't noticed, but it looks like I have 2 versions of 5.1 [or LGs version of it] running at once. everything seems to work, but it does look confusing at times.
The bottom 'home row' of icons for "Bk, home, All" is hwere its most apparent: 2 slighlty different size icons, one superimposed over the other.
Same with the 'notifications bar' at top.
Anyone offer explanation/resolution?
Thanks.
