Trim/Register/Bleeds marks on PDF import

[vikram]

In CS5, when a PDFx1a is imported/ placed - does NOT preview or print the marks on PDF that has all marks showing and set to print. Also - same problem on Quark 8.0.
Same PDF does preview perfectly with marks on Quark 7.0 and CS3/ CS4..any reason?
