Fullscreen slider custom arrows doesn't show up

[Loris]

Hello,
I am using the fullscreen slider addon, with vertical slides. I have uploaded custom arrows in the fullscreen slider option, but these doesn't show up.
Wordpress, Laytheme and Addons are up to date.
Does anyone has an idea how to fix it?
Thanks
L
