Currently moving no pc to look at this closer but what is your health float at for max health?
usually widgets display 0-1 for a progress bar. But if your damage isn’t scaled to your health right or umg not showing health right could be a problem.
For instance if you use a float for health of zero to one you’d likely want to make sure your damage is applied in that range or you use 100 health for example and divide it by 100 in umg to get the 0-1
