Gallery Page shows blanks for images I deleted

Hi, I created a gallery page using the Colorway Theme. I added a gallery of images. It looked fine except I noticed I had accidentally added a couple of photos twice. So I deleted the duplicates from the media gallery. Now the gallery page has three blank boxes.

Is there any way to correct this? I tried changing from a gallery page and back again, but this not help. If it's some info in the database, I could correct it if I knew where to look.

The page is here: http://www.venetianspamobile.com/special-events/

There are three blank images at the bottom of the page. These are the three I deleted.

Thank you in advance for your help.

Okay, sorry. It turned that there were three videos also attached to this page...this was done by another author. I unattached them with an unattach plugin. All is fine now.
