2 posts Carousel on the same page (1 for blog, 1 for services)

Hi ! This theme is superb !
I have a problem : I want to set 2 posts carousels on the home page. One for blog posts, the other one for services.
But it doesn’t work properly : – Services post-carousel shows 3 posts but I have set “four columns” – Blog post shows huge posts instead of small scrolling ones
If I set only one post carousel it works as parametered.
Here is the code :

- Services (no column, full width)

[posts_carousel heading="Nos services" post_type="services" order_by="order" order="ASC" limit="10" meta="no" excerpt="yes" excerpt_char_limit="72" exclude_current="no" width="four columns" scroll_by="4"][/posts_carousel]

- and further in the page, the blog (in a 2/3 column) :

[posts_carousel heading="Derniers articles" post_type="post" category_slug="" order_by="date" order="DESC" limit="10" meta="yes" excerpt="yes" excerpt_char_limit="64" exclude_current="no" width="3 columns" scroll_by="3"][/posts_carousel]

Thanks for your help ! K. (France)
