Comments not centered

Hi there,

after an update of the theme and wordpress to 4.4.2 I seem to have an issue with the Advanced Slider.

I am using the template 3 to only display text on a comments page.
All content is displaying without any problem but the alignment is not correct. When going full screen all content seemed to be aligned to the left instead of centered as per slider settings.

I had the issue before and you helped me solving it.
See https://www.ads-software.com/support/topic/test-posts-done-show-in-slide-show?replies=14 for details. However, this time your solution cannot be applied.
If you need any more details please let me know.

Any idea? and thanks in advance.
Lars
