Hi there
I was rendering a scene in unreal engine 5.4.4 and encountered with lighting problem.

as you can see in pic 1 which i took it from editor viewport, shadow of the mesh is in the right side of it and i have only one directional light (movable mobility)

as you can see shadow direction is in the opposite side of my directional light shadow.

is this usual? how can i find that unknown light?
i tried building lights also check the force to remove before builds (something like that in world setting) and build light again and again but nothing has changed.
i will be appreciated if anyone can help me.

I fixed the problem.
After trying many ways to solve the problem, i tried this one and fixed it.
First i deleted the DDC and ZEN folder in
C:\user%username%\appdata\local\unrealengine .
I had some assets and directional light and etc in my default level ( the level which opens in my project stratup), so i delete all of’em in the default level.
Then i entered to my problematic level and tried to render again and this time every thing was alright.
