For some reason, if I sort my collection by Name (A-Z) one of the items in the collection appears in a row by itself. If I reverse the sort (Z-A) its no longer an issue. I also saw this happen when using “Random Order”…
When I preview the site it seems that the podcast categories are aligning to one column instead of two, has there been a design choice made recently where the direction is different now?
Regardless, achieving the layout without anykinds of gaps would be a great job for using Flexbox for if you haven’t explored that option yet.
Are you using a mobile device? On desktop it should definitely have two items in a row. I didnt configure the collection list layout, IIRC it has the default settings. I can see if that uses flexbox or not.
