I need help with editing in the blueprint viewport

Hi, i’m working on the chunk modules for my game, and i’m converting it to be completely 1 to 1 tile based. when I try to move these tiles at the same time, they all move at different rates (moving the gizmo the same amount moves each part at different rates than the previous ones)

I don’t know what to google to figure this out, could I get some help? I want to move them all at the same rate
