Flare on the R5

[trkinsptr]

I am getting vertical flare streaks on my new R5 in night photography from bright lights.I do night photos of trains which have very bright headlights.When I use EF canon and sigma lenses with the adapter on the R5 the vertical flare streaks show up. The same lenses on my 5D4 don’t get the flare streaks.
