Not all Reviews are not displaying

the page builder is Oxygen builder.

https://excruiser.com/product/all-terrain-electric-skateboard/

there are 3 reviews, as shown on the image attached:
1 is left by a real customer, and the other 2 are written on my self, just testing the review function.

but only the customer left review shows on the frontend, the other 2 are not shown
please help, thanks.

ps:
I’m using this code to show reviews on Oxygen Buider:
<?php echo comments_template(); ?>
