Changing/Overriding Slider Value Caps

Hey, have tried Googling and searching Reddit and Adobe Community, but can't find anything relevant.

Was following a project tutorial, and in the video, the creator sets an inner shadow size to 450, however mine caps at just 250.

Only thing I could think of trying was a slider control, but while I can set the slider above the cap, the effect still gets capped.

Anyone know why the value is capped for me, why its uncapped (or has a different cap) for him or how to change/override it?

Thanks!
