Sub Gallery Not Visible

I have a page that I have disabled "browse folders" on in the CSS filed on the theme design. 

Does this automatically disable sub galleries displaying from within sub galleries?

I don't recall this being an issue on the previous pages/themes I've done this on.

When I tested this in an archive gallery that is part of this same category, I can see the sub gallery listed...but in the current gallery I am working in, it is not showing.

I'm not sure what I have done to cause this and would love some guidance.

I am attaching two screen shots. One shows Testing 1 with a sub gallery titled Testing 5 that you can see (this is from the previous year's gallery that is now archived).
The other shows the current gallery that has a sub gallery, but it goes from the title straight into the images and I can't see the sub gallery at all.

You probably checked the option in the attached screenshot. 

Also, in the 5.0 update:

• Added the option to display or not the browse folders button that navigates the sub galleries for 1 level sub galleries and multi level sub galleries in Settings -> Photo Settings.  

Yes, found that! But what setting do I use to not have subgalleries visible on the page? I remember having to do this previously, but I can't find the box I should be clicking. We cannot display contract student info on the page, but I am failing to remember how I achieved that previously.

But what setting do I use to not have subgalleries visible on the page? 

I don't understand. The do no display sub galleries on website will do just that.

Sorry for not being clear, I am having a hard time articulating this.

In previous years we have had it set to where the sub galleries are not visible on the main page that our seniors access....but the sub galleries within those sub galleries was still visible to the student. 

Our setup is-
MAIN PAGE- the only thing visible was/is the "find my photos" box.
Student enters Passcode and can see their sub gallery...as well as any sub galleries we make within that sub gallery...upgrade images, digital file purchases, etc. 

For some reason, with this most recent gallery, when they access their individual sub gallery, the sub galleries within that are not displayed. The box for not displaying sub galleries was checked, so when I unchecked it, and viewed the page as a parent, it was listing all of the individual sub galleries are being displayed, which is not how it has been in previous years. I just cannot remember the method I used for them to not be on display on the main page, but students can still see any sub gallery within their own sub gallery.

The only thing different this year is that this section has a new "theme". I looked through the theme set up over the weekend and cannot figure out which setting needs to be changed. 

I don't know how you would have accomplished that before. I'm thinking you just didn't have sub galleries within sub galleries before or you had each student as a main gallery and not in sub galleries.

With "do no display sub galleries on website" checked, it won't display any sub galleries at all within that gallery.
