Buttons hanged are not moved

Hi,

The cause of the problem is most probably a conflict with another plugin or the theme.

Could you please, firstly try to change the theme to see whether the issue will occurred again.
If it will please, deactivate all your other plugins, except slider wd and see whether the issue will be solved.
If the problem will not be occurring, please activate plugins one by one and check slider wd simultaneous, to find which one is causing the issue.

Thanks! Have a great day!
