Hello @jonghopark,
Thank you for reaching out,
Could you confirm if this issue occurs only with the OceanWP theme?
To test this, please install a default WordPress theme(Twenty Twenty, or a lite theme like Storefront or Hello Elementor) and check the issue again.
If the issue persists, kindly get in touch with the author of your third-party plugin.
