It does seem that LibreOffice offers a practicable solution for editing Steiner pages, but not ever having tried to do so myself, I have no idea how time consuming or finicky this may or may not be.
I wondered though as an alternative, as to how easy it would be to recreate the modified page from scratch using AlbumEasy. This is what I came up with after 20 minutes.

Admittedly not an exact replica - but most of the differences are inside the stamp boxes which will eventually be covered, and of course, not having access to the original page, box and font sizes are just rough guesstimates.
I do have the advantage of being more than a little familiar with AlbumEasy, but on the other hand a good part of the 20 minutes was spent "borrowing" angore's images.
Also, subsequent pages in the same album can be created far faster as much of it consists of cutting and pasting.
Here is the complete AlbumEasy file which generated the page:

All else being equal, I think that the AlbumEasy solution offers the advantage of much easier modifications in the future. Page sizes could be changed from Letter to A4 or to any custom size for that matter, borders could be removed or restyled and margins can be alternated left and right for double sided printing etc, All of this could be done in mere seconds whether for one page or for a whole album.
