Sudden Lumen reflections quality drop

Hi,

We have a scene with Lumen reflections on a glass material. In the screenshot below, we are experiencing a sharp/sudden change in Lumen reflections quality where it goes from reflecting materials correctly (yellow) to almost black. For the reference, the reflected object is a single mesh with yellow material. Reflected card’s Lumen cards are set to the max of 32.

Is there a particular Lumen setting that can fix this? We tried increasing Max Distance Trace but that doesn’t change the look of the scene.
