Realtime Directional Light not casting shadows

So, I have two directional lights on my scene:
One is a baked (it was mixed before I created the realtime, so it handled both environment and characters) directional light set for environment and masked to not apply on characters.
The other is a realtime directional light masked only for characters.

The problem is, for some reason this realtime light doesn't cast shadows as the baked did back when it was mixed. How can I get shadows from this realtime light?

My baking mode is set to Indirect, if that helps.

 

On URP you can have only one directional light casting shadows. I think it applies to both real-time and baked shadows.

 

Ouch, alright, thank you!
