Subtitles are duplicated in the excerpts

Hello,
i am trying to show subtitles under each excerpt title, but the subtitle gets duplicated.

To achieve that, i have added this call before the last return statement of
tonjoo_ecae_excerpt :

show_subtitle("h3");

This is the definition of show_subtitle:

function show_subtitle($tag="h2"){
			ob_start();

			the_subtitle();
			$subtitle = ob_get_contents();

			ob_end_clean();
echo '<' . $tag . ' class="subtitle">' . apply_filters('the_title',$subtitle) . '</' . $tag . '>';
}	

The subtitles get duplicated even if i replace show_subtitle(“h3”) with the_subtitle().
Why is this?
The post page https://saranda.holiday/vacation-tips-albania-saranda/ calls show_subtitle() but doesn’t have this issue, only the excerpt has it.

Let me know ,
thank you in advance

P.S. The subtitles plugin i use is KIA Subtitle.
