Can only edit spine in 4:1 or 1:1 view when editing cover in Book module
See subject. When attempting to insert and edit text in the text boxes in one of the LR templates for dust jacket cover, I cannot get a view closer than "Fit" (in the preview panel) for any part of the cover other than the spine. I need to get closer to do a good job inserting and editing text in particular on various non-spine parts of the cover template. I have tried: clicking on 1:1 and 4:1 in the Preview panel, moving around in the center screen (but no horizontal slider displayed), or moving the rectangle in the Preview panel (as I am taught in LR videos). Adobe chat support just now said 'that's the way LR is supposed to work'. If so, that's ridiculous, since all the tricks I just mentioned work just fine when editing all the pages in the book.
I have also tried using other dust jacket templates for the cover. Same problem.
Esteemed expert colleagues, any ideas?
