Go through End Portal to Dark End?

When I enter the End through an End Portal, the End is completely dark. I can place torches to light it up. If I switch to creative mode and use a potion of Night Vision or Conduit Power, the issue is resolved.

 

I have tested this over and over and the issue occurs each time. Now, as an update, the Overworld appears dark after going through End Portal to spawn (even though it is Day Time).
