You can set the slider buttons correctly in the PPD Folder. Go to PPD/Keyconfiger

Then you change the L and R too whatever button you want to trigger the sliders. (NOTE: L stands for LEFT-SLIDE, and R stands for RIGHT SLIDE)
You can also change this in game (https://gyazo.com/246dd7ecb8d6b56be03d31ba920e34be)
Default sliders can actually also be triggered by pressing the △ button or the O button (△ for Right slider and O for left slider)
If this didn't help tell me, thanks.

hey neo.thanks for the reply. for some reason no matter how many times i change my keys the right slider is stuck on circle. and the left slider just refuse to work

Maybe the button you changed the slider too already was used?
