Views Append displays external pdf files multiple times and erratically

Hello,

I needed to merge a pdf generated with the Print module (from a Views display ) with pdf files attached to the node from which the display was composed, so I tried using the Views Append submodule. While it does seem to recognize tokens / Views rewrite patterns although it does NOT list them, the problem is that the same attachment is printed 3 times: the first time it's also only partially displayed in a a4 page, the other two times it is displayed in full in a wider format page.

I also wonder about the name of the module. To "append" means to add at the end, so a more appropriate name wouldn't perhaps be Views PDF Embed?
