Aries Editor, link to existing source - Bug?

[Paul]

I go to add an existing source to an event. When the 'Link to an existing source' dialog is displayed I sort by 'Source Description'. A source with no description is shown in the list and it has the highest source number, in my case @S129@. I've checked the raw gedcom externally and there is no such source. Is it maybe an 'off by one' loop error when building the list?
