Replacemet issue with bullets and overlapping text

We have a issue with text replacement. When we do replacement for text fragment that contains bullets - after replacement document have overlapping text.

Code snippet:

    var document = new Document("src/test/resources/pdf/test_5.pdf");
    var page = document.getPages().get_Item(1);
    Map<String, Rectangle> tokens = new LinkedHashMap<>();
    tokens.put("ICH", new Rectangle(222.25, 629.758, 242.902, 642.9580000000001));
    tokens.put("person", new Rectangle(212.402, 660.4780000000001, 244.53799999999998, 673.6780000000001));

    Map<String, String> replacementValues = new HashMap<>();
    replacementValues.put("ICH", "International Conference on Harmonisation");
    replacementValues.put("person", "individual human that providing services in connection with the Clinical Trial to evaluate the efficacy");

    tokens.forEach((searchValue, rectangle) -> {
        var absorber = new TextFragmentAbsorber();
        absorber.setTextSearchOptions(new TextSearchOptions(rectangle));
        absorber.setTextReplaceOptions(new TextReplaceOptions(WholeWordsHyphenation, REPLACE_FIRST));
        var textFragment = absorber.getTextFragments().get_Item(1);
