items displaying incorrectly in exhibit

I have a student who is working on an exhibit. She choose a page with text at the top and three rows of four items beneath. For some reason, the items are spread unevenly over four rows. There is a row with four, then one with only one in the far right, then a row of four, then a row of three.
Does anyone know why this might be happening and how we could fix it?

Will you check to be sure that all of the items in the exhibit are marked as public?

Can you post a link to the page?

I just saw that they are not public, and changed that. This is the same exhibit page that I asked about in another post, where the images are not lined up correctly either.

Sorry, we have two threads going, so I see I was repetitive above. :)

The basic problem is that the styling doesn't handle long captions well, so long captions are extending the item down too far and bumping the items below it around.

It might work to change the order of the items so that the items with longest captions are farthest to the right on each row. Not sure if that'll work, but that's the best workaround I can come up with immediately.

Thank you, we will try something rearranging them.
