Footer floating over content (tables)

[Marwe]

The table footer floats over the whole page and corresponding table (above), thereby overlays on content.
The div has class="card-footer search-footer" with the css selectors:

.search_page .search-container .search-card .search-footer {
  position: sticky;
  bottom: 0;
}

Disabling position: sticky; solves the floating and the element stays below the table: maybe that should be default?
