Creating a Sprite from a texture changes the location of the texture

I am still a novice…

I have created some flip books from sprites I downloaded from CraftPix, and have the character moving about fine. My attack animation causes the character to move into the air to play the animation, when it should in fact still be on the ground. I have found the problem. When I create the sprites from textures, the attack sprites are not aligned to the bottom of the sprite like the others. See the pictures below.

I used Unreal’s Built in default functionality to create the sprites and flipbooks. Surely there is a way to adjust the position of the texture in the sprite so that it is aligned to the bottom or am I tackling this in the completely wrong direction?
