Breadcrumbs on the current page

Question

I am currently implementing my breading cramps as follows:

<div itemscope itemtype="http://data-vocabulary.org/Breadcrumb">
    <a href="HOME URL" itemprop="url">
        <span itemprop="title">HOME TITLE</span>
    </a> > 
</div>
<div itemscope itemtype="http://data-vocabulary.org/Breadcrumb">
    <a href="1ST LEVEL URL" itemprop="url">
        <span itemprop="title">1ST LEVEL TITLE</span>
    </a> > 
</div>
<div itemscope itemtype="http://data-vocabulary.org/Breadcrumb">
    <span itemprop="title">CURRENT TITLE</span>
</div>

As you can see, I did not provide the URL for the current page, which would be redundant. But when I try to use the Google testing tool , I get an error message indicating that the URL for the current page is not available.

Given this, I have three options that I can think of.

I specify the URL for the current page:

<div itemscope itemtype="http://data-vocabulary.org/Breadcrumb">
    <a href="HOME URL" itemprop="url">
        <span itemprop="title">HOME TITLE</span>
    </a> > 
</div>
<div itemscope itemtype="http://data-vocabulary.org/Breadcrumb">
    <a href="1ST LEVEL URL" itemprop="url">
        <span itemprop="title">1ST LEVEL TITLE</span>
    </a> > 
</div>
<div itemscope itemtype="http://data-vocabulary.org/Breadcrumb">
    <a href="CURRENT LEVEL URL" itemprop="url">
        <span itemprop="title">CURRENT TITLE</span>
    </a>
</div>

I simply show the current page title without including it in the labeling of structured data:

<div itemscope itemtype="http://data-vocabulary.org/Breadcrumb">
    <a href="HOME URL" itemprop="url">
        <span itemprop="title">HOME TITLE</span>
    </a> > 
</div>
<div itemscope itemtype="http://data-vocabulary.org/Breadcrumb">
    <a href="1ST LEVEL URL" itemprop="url">
        <span itemprop="title">1ST LEVEL TITLE</span>
    </a> > 
</div>
<span>CURRENT TITLE</span>

I do not show the current level in breadcrumbs (I do not want to do this):

<div itemscope itemtype="http://data-vocabulary.org/Breadcrumb">
    <a href="HOME URL" itemprop="url">
        <span itemprop="title">HOME TITLE</span>
    </a> > 
</div>
<div itemscope itemtype="http://data-vocabulary.org/Breadcrumb">
    <a href="1ST LEVEL URL" itemprop="url">
        <span itemprop="title">1ST LEVEL TITLE</span>
    </a>
</div>

What do you think I should do?
