@nimuravka, from the Appearance -> Customize go into each section that has its individual option to set the number of words limit. You need to increase these words limit so to make sure it has greater value than the content you have for each of those sections.

For e.g. to configure for Service section go to Appearance -> Customize -> Home / Front Service Sections -> Service Options

Hoping this would help you out !

Hello @MichelleG

To solve your issue at first you need to create a child theme. Below is the reference for creating a child theme.
Child Theme

After successfully creating and activating the child theme paste the following code in your functions.php file of the child theme

You can also use the plugin to create the child theme . Please refer to the below link
Child theme

function biography_words_count( $length = 25, $biography_content = null ) {
	$length = absint( $length );

    if ( '' != $biography_content ) {

        $biography_content = strip_shortcodes( $biography_content );
        $biography_content = str_replace( ']]>', ']]>', $biography_content );
        // $biography_content = strip_tags($biography_content, wpse_allowedtags());

        //Set the excerpt word count and only break after sentence is complete.
        $excerpt_word_count = $length;
        $excerpt_length = apply_filters( 'excerpt_length', $excerpt_word_count );
        $tokens = array();
        $excerptOutput = '';
        $count = 0;

        // Divide the string into tokens; HTML tags, or words, followed by any whitespace
        preg_match_all( '/(<[^>]+>|[^<>\s]+)\s*/u', $biography_content, $tokens );

        foreach ( $tokens[0] as $token ) {

            if ( $count >= $excerpt_word_count && preg_match('/[\,\;\?\.\!]\s*$/uS', $token ) ) {
                // Limit reached, continue until , ; ? . or ! occur at the end
                $excerptOutput .= trim( $token );
                break;
            }

            // Add words to complete sentence
            $count++;

            // Append what's left of the token
            $excerptOutput .= $token;
        }

        $biography_content = trim( force_balance_tags( $excerptOutput ) );

        return $biography_content;
    }

    return apply_filters( 'biography_words_count', $biography_content );
}
