Can’t see my portfolio item’s preview image after adding it in Avia Builder

I am trying to see that the preview image added for my portfolio item is visible in Portfolio Grids, or Portfolio Page in WordPress. It doesn’t work. I tried clearing cache but it didn’t help.

Versions:
Theme Enfold: 7.1.1
Wordpress: 6.8.1

Steps:

1) Go to Portofolio Item Edit Page
2) Add image in Gallery Preview
3) Save
4) Check the Portfolio Items Page
I can’t see the image updated.

Images:

Please help
