While working on an image, I came aware of a small point in the "origin" of the drawing (upper left corner).  This is only displayed when one or various text on path objects are selected. I worked on several images with text on path objects which I'm now compositing into another file (for cleanness). Selecting one or several objects from one of the drawings, copying and pasting it to the new drawing is just fine (as all the relations of text to their paths are preserved). However when I selected other elements with similar characteristics and pasted onto this new "master" drawing, all the text on path elements got disaligned.

How can I keep aspect and why does this happen?

Maybe I'm doing things the wrong way (copy/paste) and I should be importing files or some other way?

TIA!
