HP Bar showing more than CurrentHP Value

My max player health is 100, and when my player reaches half health its showing 75% instead of 50%. My health system seams to be working fine, its just the slider that is always showing 25% more than I have. I have watched Brackeys health bar tutorial 2x over to make sure and it’s still not right. How to make a HEALTH BAR in Unity! - YouTube!

you can just substract 25 from the health before applying it to the slider
