How to fix this? The rest of the widgets get back to default value when you slide one of the widgets

Basically, I want to create an adjustable Brightness, contrast and saturation with different slider widget each. But when I start to slide one of the widgets, the other 2 widgets are going back to default value. I want the value of other widgets stay when you slide one of them. Please help me to fix this. Thank you

this is my widget blueprint

Hello You need to create separate variables for each slider (brightness, contrast, saturation) and update only the corresponding post-processing setting each time a slider changes, without modifying the other settings.

problem solved. Thank you for your help
