I am getting multiple tooltips when using typedhandler+annotator

Following is the code I wrote

public class SimpleAnnotator implements Annotator {

    @Override
    public void annotate(@NotNull PsiElement psiElement, @NotNull AnnotationHolder annotationHolder) {
        SyntaxHighlighter syntaxHighlighter= new SyntaxHighlighter();
        if (!syntaxHighlighter.annotateoffsets.isEmpty()) {
            for (int i = 1; i < syntaxHighlighter.annotateoffsets.size() + 1; i++) {
                int startOffset = syntaxHighlighter.annotateoffsets.get(i).get(0);
                int endOffset = syntaxHighlighter.annotateoffsets.get(i).get(1);
                String tooltip = syntaxHighlighter.tooltips.get(i-1);
                TextRange range = new TextRange(startOffset, endOffset);
                Annotation annotation = annotationHolder.createErrorAnnotation(range, "");
                annotation.setTooltip(tooltip);
            }
        }
    }
}
