Hello,

I have logged into your website. The issue is caused by the name of the products and slug because you added the name only as 1280, 640, etc.

I have changed the name and slug of a product and it is working.

https://www.tarms.com.my/staging-1/product/cleaning-machines/floor-sweeper-machines/sweeper-ride-on/floor-sweeper-1280/

which clears that the issue is not from our theme. You can try changing the name and slugs of the products.

Best Regards
