Library Graphics aren't accurate. When placing a logo 'as a copy' anchor points are out of place

(specs at bottom)
The vector graphics I add to one particular CC Library change over time... in case it's not obvious the 'B' should not have the jagged connections between the baseline and the right hand vertical.
Various copies and versions of this brand logo come out wrong / irregular when placed as a copy. These vectors did display correctly at one point. When I notice it's gone wrong I go back to the orriginal logo file and add it to the library again... it works for a while then eventually the same things happen. This does not occur when the same graphic is 'placed' or dragged from the library wondow to the artboard.
Thanks in advance
