The Appearance of My Widget Title is weird

I really love this plugin. You are a great guy. But I’ve found a problem. The appearance of the image gallery is fine. But, it changed the appearance of my widgets title.

Here is my site https://agendurianmedan.com and in the homepage the widgets title are fine.

And I put the image gallery in two pages. Here is one of them. https://agendurianmedan.com/produk-harga/daging-durian-medan/

Please visit the link above and you’ll find something weird with the appearance of the widgets title where I put the image gallery.

Would you like to help me please?

Thanks.
