Problem with the view mode
"unformatted list", article list displayed incorrectly in Olivero theme (didn't try other themes), the list got shrunk in width: Example of the issue and: Example of the correct list view
Probably caused by the Olivero theme. Some views work well, others are affected. Unformatted list or Grid - it doesn't matter, the field of display in frontend is defected. On mobile devices it is more apparent.
