Can't move to the second animation frame.

I’m trying to create an animation in UE and I cannot move the to the next frame. I get the range between 0-1 frames and it doesn’t matter how many frames I insert I just cant move to them I’m stuck at frame 1. How do you move to the next frame ? This happens all the time I create an animation asset from scratch in unreal, I’ve only been able to create animation by duplicating other animations(in which I can scroll freely through the timeline) and resetting all the key frames, it’s the only way I can move beyond the first frame
