Recent versions of Word 2011 for Mac seem to have had changes implemented which cause Word to compress ALL embedded graphics, even when told not to. This compression strips the embedded ID and prevents our products from accessing the graphic.
There is currently nothing we can do to prevent Word from compressing the graphics. The problem lies with Word 2011.
We are keeping a close eye on this issue and have reported the compression issue to Microsoft.
In the short term, old graphics can be accessed with the History button.
