[Geany Portable v1.24] Unable to set row highlight color

Hello everyone,

I am experiencing a problem with Geany Portable v1.24.

When I select the editor's color scheme via [ Menu > View > Change Color Scheme ], all but the row highlight color is set, which remains the default opaque light grey.

Is there a setting or tweak to change this or is it perhaps a bug? Is anyone else having the same issue?
