Although it is not a solution, I will post the code to hide it with CSS just in case.
body[data-page=home] div#journals div.journal-item:not(:has(div.blocks-container div.ls-block+div.ls-block)) {
display:none;
}
If there is a journal that has only the first line in Journals other than single pages, it will be hidden. Due to side effects, it must be opened from a single page.
