Issue with Field Name Order in PDF Script

Hi everyone,

I'm using a PDF script that works well for ordering the field names by "Order Tabs by Structure" (exact order). However, I've noticed that for some of the order of the field names changes unexpectedly.

Has anyone encountered this issue before? Is there a way to ensure that the field names always stay in the correct order, regardless of the PDF structure or any changes in the document?

Any help or suggestions would be greatly appreciated!

Thanks in advance!
Script is below:

var fieldArray = [];
for (var i = 0; i < this.numFields; i++) {
    var field = this.getField(this.getNthFieldName(i));
    var fontSize = field.textSize;
    var fontName = field.textFont;
    var rect = field.rect; // Array of coordinates [left, bottom, right, top]
    var width = (rect[2] - rect[0]) / 72; // Convert points to inches
    var height = Math.abs((rect[3] - rect[1]) / 72); // Convert points to inches and use absolute value
    fieldArray.push({ name: field.name, tooltip: field.userName, fontSize: fontSize, fontName: fontName, width: width, height: height, type: field.type, top: rect[3], left: rect[0], pageNum: field.page });

}

// Sort the fields by page number, then by their top position (from top to bottom), then by left position (from left to right)
fieldArray.sort(function(a, b) {
    if (a.pageNum === b.pageNum) {
        if (b.top === a.top) {
            return a.left - b.left;
        }
        return b.top - a.top;
    }
    return a.pageNum - b.pageNum;
});

console.println("Field names, tooltips, font sizes, font names, widths (inches), and heights (inches) in the document:");
for (var j = 0; j < fieldArray.length; j++) {
    var fieldInfo = fieldArray[j];
    var widthText = fieldInfo.type === "checkbox" ? fieldInfo.width.toFixed(2) + " inches" : "width";
    console.println(fieldInfo.name + "; " + fieldInfo.tooltip + "; " + fieldInfo.fontSize + "; " + fieldInfo.fontName + "; " + widthText + "; " + fieldInfo.height.toFixed(2) + " inches");
}
