Hello Roj,
We checked your website many times with different computer as well although we can’t find the issues. So, please provide the screenshot if you have so that we can try to find the similar issues on our demo as well. We will keep checking your website and try to find the issues as well. Keep patience.
Can you please try once by deactivating the installed plugin? Make sure you are using the latest version of theme and WordPress as well.
Let us know how the results.
Regards
