I hope you are well today and thank you for your question.
Would you mind if i log in to your site and do some troubleshooting? If this is ok then could you please share me your site log in details privately by adding them in the box having text “Click here to share private content. Only you and forum moderators will bee able see it.”?
I could confirm the issue on my test site which occurs when using Masonry 2.0 Standard blog style therefore notified the theme developer about this so that it will be fixed.
The issue will be fixed ASAP.
In the meanwhile you can try resolving the issue using any other blog style as shown in the attached screenshot.
