Bug Description
13 of 17 Wallpaper groups at symmetry tab of clones behave erratically.
I attached 17 clones of a basic shape. 13 of 17 symmetries are not the way they expected to be.
P1, CM, PG, PM behave normally.
Others are broken.
What is expected from symmetries?

A wallpaper group (or plane symmetry group or plane crystallographic group) is a mathematical classification of a two-dimensional repetitive pattern, based on the symmetries in the pattern. The pattern produced should have equal distance between tiling blocks. Some symmetries are hexagonal and I am not sure how parameters in other tabs apply to a hexagonal symmetry.
I attached tiles produced by Inkscape clone tool. Please compare them to tiles in reference sites.

I haven't checked each of your SVG files but those that I peeked into all have a translated layer group which indicates that your issues are due to the same underlying cause as reported in Bug #168651 “"Tiled Clones" inside transformed groups broken”.
Can you test if your wallpaper groups also fail in new default documents that have not been resized or changed in format or page orientation?
