Hello Seeder98,
The fact that I can reproduce this issue on my end leads me to believe that this is a bug. This issue seems relatively similar to another users issue.
As in the other thread, there is a Bug entered. The number is UE-7019. I can add this thread to the list of comments on the bug in hopes to speed the process along of handling this issue.
Currently not all lights are supported in all views. Orthographic views seem to be causing the most issues.
Thank you very much for reporting this. I will keep you posted on this bugs progress as it comes in.
Thank you,
