Steps to see issue:
1) Create a new Passage Guide Template. Mine was called "Removed Guide"
2) Open a new Passage Guide, using "Removed Guide".
3) Set its verse range to "Matt-Luke", give it a name (so it saves)
4) Delete the template "Removed Guide"
5) Display "My Content" that used to display the item in (3), but notice that now there is an empty blank line in its place (Yellow Highlight)
It seems that my saved Passage Guide is still "saved", but its template is now gone, so it does not display correctly on the "My Contents" portion.
