Phantom white square appearing only on Safari

I just delivered a portfolio website.

The client discovered that only on Safari browser and on an specific page a strange white square appears. It looks like a check box and it is not an actual object I have put on the website. It sits floating between divs.

Here are some screenshots, you have to open the site on Safari to see it:

Any idea?

Here is my site Read-Only:

hi @Hector_Munoz_Huerta it has something to do with overflow: scroll and it probably will be some part of scrollbar.

You can just add custom code to hide scrollbar, but I do not know why you have on form overflow : scroll in first place


Thanks a lot Stan, I recycled a class to create this section, this is the reason for the overflow. No I can fix it.
