Final Bar-line Looks Just like Double Bar-line In V2

Hello!

As the heading says, in Dorico V2, the final bar-line looks just like a double bar-line.

Is it me, or, is there a switch I need to turn on?

There is an option for double thin lines for repeat barlines in Engraving Options > Barlines. Otherwise, try selecting the barline and pressing . There may be an explicit barline set.
