Spotlights only working on High and Low Scalability, but not on Medium?

Hi I’m very new to all of this so I’m hoping this is just another case of me overlooking the obvious. I have spotlights set up on my level and they work how I’d like them to whenever overall scalability is set to Low or High as pictured here:



But whenever scalability is set to Medium they appear to be off like this:

The spotlights are set to Unitless, though I have tried them on Lumens and Candles as well with the same results. I thought they were turned off because of the reduced quality, but why would they work correctly on low but not medium?

I wasn’t sure of any relevant blueprints to post but would be happy to share any and all relevant information for any help!

Thanks!
