Navigation Menu is not appearing in some exhibit pages

I started using the Image Annotation Plugin in my exhibit and I noticed that the pages where I added Annotation Blocks do show the Navigation menu any more. What is strange is that everything looks fine if I try to see the Public page as I am editing the exhibit, but if I try to see the exhibit using the link to the site, none of the pages that have an annotation block will show the navigation menu.

I am using Omega Classic 3.1.2 Exhibit Builder 3.7, and Exhibit Image Annotation 1.2

Any assistance will be welcome
