For controller, is +levels of skills not showing on skills within cast on X a visual bug or real?

I've played through GeForce Now with both m&k and controller along with Xbox. With m&k, hovering over the skill within a cast on X skill shows the + skill levels being applied.

With controller input on both GFN and Xbox, the only way to hover over the skill within a skill is to manage sockets which does not show the + levels being applied.

If this is a visual bug that can't be fixed within the skills menu, it would be helpful to add a level indicator to the advanced info screen above the damage calculation.
