Media Player Doesn't Show Backdrops on Detail Screens?

[kipoka]

i just installed the media player for windows and the player doesn't show/use the backdrops on the detail screen for each movie or tv show. only the logo is shown.

backdrops are enabled in the settings and jpg files are included in the libraries.

i am using the elegantfin custom css with some additional commands that update the home screen with a grid view. here's the code.

it's working in the chrome browser btw.

any clues on how to solve this? thanks
