Page cropping problem in Acrobat XI

I have a title built in InDesign that I export in PDF for the printer. I discovered over successive runs that I needed to shift the y axis a tad and widen the gutter to get the best production results. Here is the routine for doing so in Acrobat Pro IX:

in Acrobat

Document /Crop Pages / ChangePage Size / Custom:width 6 in; height 9 in. [ set for each operation ]

Adjust y-axis (height) of text block

Y offset: - 0.15 (check shift visually)

Page range = all

apply to: odd and even pages

Adjust recto x-axis placement

X offset: + 0.13  (check shift visually)

I had to produce an new PDF body file for the first time since switching to CC (Acrobat XI), and when I finally found the page cropping dialogue, the above routine blew up the book completely. There wasn't a single character visible in 300+ pages. I take it that Acrobat XI has different ideas about cropping pages, but I couldn't see where the problem lies. The dialogue boxes look the same. The commands are the same. Only the results are different. ??

Any help much appreciated.
