Halls of Valor, Frenrir 2nd phase

In halls of valor on the Fenrir fight when he runs off to lick his wounds or whatever, Why is the trail blue and not blood red? My friends took screenshots of their screens and its red. I know a dumb issue! Haha But it kills me not knowing why my trail to 2nd phase of Fenrir is blue and not red. I checked everything reset all my color settings and im not colorblind. Looked things on google and nothing pops up. Do i have a rare bug or do i have a shiny pokemon Frenrir?
