Why, when adding text, to the beginning of the already placed IPTC text in the "caption" box, and using the selection 'append' the 'added' text does not appear after clicking 'save' & the arrow box to move to the next image on checking the picture info afterwards in my documents folder ? Sometimes, even the original IPTC caption text is actually being copied. Is there another setting 'outside' of the IPTC box that I should maybe check ? I use a MacBook.
