problem with IOR

Good morning everyone,
with the latest version I think there is a problem with the IOR in the reflection, I send you a screenshot, in the section A the IOR is active in the second one I deactivated it from the materials, I think when active there is a bug, just see the inside of the violet box and the furniture in the corner.
The inside of the box should be the same colour and not white.
I use v-ray for sketch up updated to the latest version and a mac studio M1 Ultra updated to the latest version.​
