My apologies for the delay.

If you wish to disable the animated text in the slides you can edit the code located in the scripts.php file located in the js folder of the theme.

In your Admin Dashboard, navigate to Appearance > Theme Editor, select the js folder then select the scripts.php file.

Delete line 53 to 60 and save your changes, see screenshot https://www.dropbox.com/s/jvrjdoy27c4rpip/serenity-animated-slider.PNG?dl=0
