Only two images and scattered

Once, a couple of years ago, I used Slider CK to show the brands my customers works with.
All worked well: logos scrolled smoothly.
Now I see that only the first two logos (of six) are showed, then the slide starts again from the beginning.
I don't know which was the update that messed up the configuration.
So, I read the discussion here , but it did not fix the problem.
In the attached image you can see my present settings.

You can find the page here
How can I fix the problem?

Hi
by my side I see 6 logos running ...please clear your browser cache and tell me
CEd

Cleaning the browser cache was not enough. I had to:

1. clean the Joomla and extensions cache
2. clean the browser cache
3. access the site anonymously (in private mode)

And then i could access the site normally.
It's fantastic the number of things that can be messed by the cache!

yes I agree. It is fantastic ...
