Long press your song on the library screen, tap "Edit Song", go to the Files tab, tap the "Page Order" field, tap the three dots at the top right and tap "Update PDF with Current Page Order". That will flatten all the PDF pages, so if it was 1-7,1-7, it will become 1-15 (this modifies the underlying PDF). Then you can copy/paste using the snipping tool and it will not cause the problem you described.
