Furnaces do not create light at all

When burning coal in a pitch black area to create light in survival mode, the furnace did not give off any light as it usually does. This most likely has to do with the RTX and I encountered it randomly. I am unsure of the replicability. The screenshot is the particle of the furnace burning but as you can see there is no light. It doesn't affect the gameplay really but it does not work as intended.
