Todo Comment Shows Twice In ToDo Window

In my plugin I am getting todo comments appearing twice in the view for the same item.

Once without the closing comment marker and once with it.

I am stumped on why it happens. I tried to figure it out but to no avail. It must be collected from two different places.

In the past I had some changes to the spell checker clobber ToDo items in the view but cannot remember if it was spellchecker extension or lexer related issues.

I have spellchecker.supportextension and a lang.commenterextension and a todoIndexerextension which looks like this:

public class MdFilterLexer extends BaseFilterLexer {
    public MdFilterLexer(final Lexer originalLexer, final OccurrenceConsumer table) {
        super(originalLexer, table);
    }

    @Override
    public void advance() {
        final IElementType tokenType = myDelegate.getTokenType();
        if (tokenType == MdTypes.COMMENT) {
            scanWordsInToken(UsageSearchContext.IN_COMMENTS, false, false);
            advanceTodoItemCountsInToken();
        }
        myDelegate.advance();
    }
}

Any insight or suggestions where to look would be greatly appreciated.
