It seams that you had your grid set to 25mil some time back.
red lines: your current grid
blue lines: additional grid points you would get if you set your grid to 25mil
You have some options going forward.
option 1: do what @keruseykaryu suggested.
option 1a: maybe don’t redo everything. you can set your grid to 25mil temporarly and move everything that is not on the 50mil grid so that it aligns with it.
option 2: if you don’t care about the looks of your schematic, just set your grid to 25mil and stay with that.
