Gallery

Hi,
After updating to WordPress 5.9, the Gallery images are no longer displaying the collage view in mobile (desktop view is working fine).
An example of where this issue is occurring: https://easyindiancookbook.com/instant-pot-vegetable-pulao/#step-by-step-instructions

My other site which is using WordPress 5.8.3 does not have this issue.
An example of the working Gallery collage: https://spicytamarind.com.au/eggless-tutti-frutti-cupcakes/#step-by-step-instructions

Wondering if anyone can help with this. Thank you!
