Secondary images / child images not showing properly

-- url of the page with the problem -- : bromarprintstore.com/maine-maritime/prod...tical-business-cards
-- HikaShop version -- : 6.5.2
-- Joomla version -- : 5.4.7
-- PHP version -- : 8.3.31
-- Browser(s) name and version -- : chrome

On my product pages the child images are showing at 25px high and 100% wide, distorted. Not sure what is causing this. Screenshot here, the site is password protected, but I can provide credentials if necessary. snipboard.io/fBYLiQ.jpg

Please advise how to fix this so they are back side by side
