Replacing cells

I’ve been experimenting with updating/replacing cells, using both singular and globally, an old logo with a new logo, it works to some degree. I did an update on the old cell prior to replacing with the new cell. Right now even though both were created with a similar insertion point, the new cell is not placed as expected, in the old cells location. When attempting to do the replace globally it simply didn't work on a test set of drawings in a seperate folder.
