This plugin conflicting with my ‘show more’ button on homepage

Hi, I’m facing a major problem with my show more button which is located on the homepage after activating this ultimate member plugin. I’ve checked all troubleshoots using ‘wp health check’ plugin and that also indicates that ultimate member plugin is conflicting with the show more button. I love your this plugin and wanna use it. Any idea of how can I get rid of this conflict problem?
Thanks.
