Shaders not applying at launch in RetroarchPlus (Nvidia shield)

Hi everyone. I have a problem for which i feel stupid not finding a solution by myself. I’ve installed RetroarchPlus on Nvidia Shield Pro (2019) Everything works fine except that the shaders i’ve specified for my cores dont automatically apply when Retroarch launches. Everytime i launch Retroarch, i have to go in the Quick Menu / Shaders to set the one i want, Wheni close Retroarch and relaunch it, the shaders configuration is lost. I’ve tried to save per core, per folder, i don’t know what to do and what i’m doind wrong…
