No worries;) Most probably, you have selected a template that uses album or page names as navigation elements. If you have previously set album and/or page names to "hidden", such design will not be able to display anything. You might see an empty page. Please ensure that your album titles and/or page titles are not set to "invisible" when you select a new design template.
1. Expand the page
2. Check if the album title is set to "hidden" (the name is struck through - see below image A:)
3. Click on album settings and switch off "hide album title in the navigation" - image B
