I have looked at your output document (thanks) and everything looks normal, apart from the extra, wide column at the right-hand side, which I can’t reproduce.
Is that what you are concerned about?
Other than that, this is exactly what a ‘compact’ formatted eaDocX Matrix Report should look like: it’s useful where there are a very large number of columns, which are too wide to fit into a page, so ‘compact’ style lista rows and columns down the page.
A 50×50 matrix will JUST fit into a Portrait-orientation format, A4 page when done in ‘normal’ style, as we write the column text vertically.

What were you expecting ?
