Lightbox alignment problem

Hi everyone!
I am new to Wix and coding. Even though I am liking the simple yet effective features of the wix site builder, there is one element which I am unable to fix - the Lightbox.
It is a very important element for any site.

I am trying to create a drop down menu which will contain certain images. I created a button and a separate lightbox.

Here is what it looks like in the editor -


And here it is in the Published live site view -

Any help regarding how to fix this is greatly appreciated! I am missing something here, I guess.
Let me know please.

Thanks in advance.
Cheers!

Hi,
If there’s a difference between the editor preview and the live site, I recommend contacting Wix Support team so that they can further investigate what causing it.

Best,
Tal.
