Smart Title Case - problem with script

Having a problem here.

When multiple paragraphs are selected the start of a paragraph is set to a lowercase

how can I fix this?

//DESCRIPTION: Converts selected text to title case smartly
var ignoreWords = ["a", "an", "and", "the", "to", "with", "in", "on", "as", "of", "or", "at", "into", "that",
         "by", "from", "their", "then", "for", "are", "not","cannot", "be", "is", "which", "can"];
var intCaps = ["PineRidge","InDesign","NJ","UMC", "FCCLA", "SkillsUSA", "d’Oeuvres", "VAT", "VIES",];
// or by creating text files named ignoreWords.txt and intCaps.txt in the same folder as the script
ignoreWords = getIgnoreFile(ignoreWords);
intCaps = getIntCaps(intCaps);
try {
    myText = app.selection[0].texts[0].contents;
} catch(e) {
    exit();
}
theWordRanges = myText.split("/");
for (var i = theWordRanges.length - 1; i >= 0; i--) {
    theWords = theWordRanges.toLowerCase().split(" ");
    //First word must have a cap, but might have an internal cap
    myNewText = "";
    for (var j = 0; theWords.length > j; j++) {
        k = isIn(intCaps,theWords)
        if (k > -1) {
