Thin translucent material and Cinecam rendering unproperly

Hello everyone,
I am doing some material research using ue5 and lumen.
I noticed that once i enter a Cinecam, my thin translucent material become discolored and doesn’t look like in my viewport ( in both Default or cinematic).

is it a bug or Im I missing some parameter in the camera property?

thanks
