I am assuming you are speaking about the program e-Sword Hotkey. A little insight into how the program looks up references, it looks for books first. In your example, Ps 103:3 Jn 1:29, it will appear that it is looking at 3 John, and the verse is 1:29 which does not exist. It will then look up Psalms 103, the entire chapter. If your text had a delimiter between the references, Ps 103:3, Jn 1:29, it will be looked up correctly. Most references I work with have some delimiter between them. The issue mainly comes up book names that several names, John being the worst. A reference such as Ps 103:3 deu 32:4, WILL be found correctly. Could I make the algorithm better? Yeah, probably. But it is not on my priority list at this time. Add a comma or semi-colon will fix the problem on your end.
And to convince you that it is looking for book references first, if your reference was Ps 103:4 Jn 1:29, they both would be found. But again, usually there is some delimiter between references and your example does not have one. One might ask, ok just look for a colon before the 4, but you also present an example of a period in the verse reference instead of a colon. But what about a Reference such as Ps 3 Jn 1:1. Is this Psalms 3 and John 1:1, or Psalms and 3 John 1:1? The algorithm as it is works pretty well, and you need to understand some of the limitations.
