Duplex print - same 1st page, different 2nd pages

[replica]

If I need to print the document in duplex, cut and stack, with the first page being the same while the 2nd pages being diffrerent.

The documents can be in two forms:

1) Separated, 1 document with 1 page as the first page, 2nd document with multiple 2nd pages.

2) One document where 1st page is the one which should be duplicated, and all pages after it are the 2nd pages.

How do I duplicate the 1st page a correct number of times and insert it after each 2nd page? I couldn't figure out how to use Insert Pages node for this.

So, for example, lets take case 2, with one file containing one 1st page and five 2nd pages.

It should turn from:

1,2
3,4
5,6

into

1,2
1,3
1,4
1,5
1,6

after duplication

Also this is assuming that "Print Quantity" parameter is not set, as this might be just a pdf dropped into a hotfolder.

I don't even understand how is this supposed to work. Sending a file through this results in nothing like what I described.

First of all, why are there even 2 copies of a job in a layout?

To rephrase the original question, to make it more clear:

I have a file, in which the first page is the back side page, and all the rest of the pages are front side pages.
I need to take that first page, and insert its copy before each front page.

So if we number each page in a file with 6 pages from 1 to 6, after processing it should look like:

1,2,1,3,1,4,1,5,1,6 - page 1 is duplicated 4 times, and inserted before all other pages

This ideally should be possible with just the Insert Pages node, but it functions in a very weird way and its not even documented fully in the manual, so I don't exactly understand how to use it for the purpose I described.

Yeah removing the 2nd column fixed it, thanks.

But is there really no way to do the exact same thing in Insert Pages Node?
