When you insert a footnote, by default the \fr is inserted for the verse where the footnote is added. However, if you are dealing with “legacy” footnotes they may be located in other verses (as your example). This is handled by the Scripture Reference Settings > Origin Options tab. There you can define if the origin (\fr or \xo) must match exactly or some other combination.
If you have “missing” origins for \fr or \xo you can insert these using the Advanced > Insert Missing Origin References tool
As a note, sometimes folks will enter a note in one verse, but want it to reference several verses. If you don’t set your selection of the Origin Options correctly this will generate errors.
