Just solved a similar issue with our setup, in this case the attributes plugin isn’t really needed if my hunch is right.
We use pa_size and pa_colour, with each variation listing their own values (make sure your masters are empty from pa_x columns).
With attributes plugin enabled, we found it’d read the colour/sizes and add them as values under attributes.
With it disabled, it Variations went in and it added the spare colours/sizes we didn’t add to the CSV the first time round.
For your one Jan, try ignoring the attribute column, or just disable the import attributes plugin,re set-up header and putting amount|gluten->1->0 in your variables column.

Just passing through, trying the same thing but with a different problem related to Product Selection not working properly.
1. Yes, ‘my-field-slug’ should be the name of the custom field you want to call/display.
2. WP can’t figure out where these should go and its causing problems. All your fields should be in between the divs in the first few lines of code. Where it says ‘//custom fields go here’

There’s a basic one with instructions included.
Check under Settings-store-import tab.

put the first box of code into a new file called woocommerce.php, upload to your child theme.
Put the second box of code into your child theme’s function.php at the bottom and reupload/save.

With all that done switch wordpress to use your child theme and see how that looks.

You may have to select woocommerce page as the page type to get it to work on certain pages.
I found replacing
<div class="<?php echo tc__f( '__screen_layout' , tc__f ( '__ID' ) , 'class' ) ?> article-container">
with
<div class="<?php span6 article-container">
worked for me in function.php as another plugin was possibly stripping/disrupting the PHP and showing the result as ‘Array’

With a little modification works with Jigoshop too. I abandoned the functions side of things and went editing the plugin’s actions directly as i didn’t thin kthe PHP from loop would parse easily.
It’s a start but needs lot of CSS tweaking

Also had this problem testing a self hosted site on own server with Jetpack.
The new code in the patch linked by Satohsy86 worked (Many thanks!)
Already backed up the original file and put new one in test folders.
