Slider text frozen

I have 5 slides and the text (heading and sub-heading) is the same for all slides. I have the correct text for each of the four following slides but each has the text from the first slide. This situation occurred after I updated the latest version of WP. Any advice will be much appreciated.

Hi,

Please double-check to have all slides different text, then clear your cache and let me know how it works then, if that won’t work, then also, please try to deactivate all of your third-party plugins and check how it works with no third-party plugins.

Best Regards,
