.SortBy("-Dependents.Count")
I fixed it. By default, the Table Layout displays a blank value if a value is zero (such as the number of pictures, number of children, number of dependants). Somehow the blank value got into the sorting routine during my last update.
There will be a Beta 17e which will have the fix for this.
.SortBy("-Dependents.Count name")
I have added 'PedigreeLink' to the dictionary, translating as 'Pedigree Link'. It is used when an adopted or foster child has a place or source associated with it and should be shown under references to that place or source. It will be included in the next release with the above fix.
