Your site CSS is overriding the display setting for the stars. Add this custom CSS to the custom CSS section of the form.

.wprevpro_form label {
display: inline-block !important;
}

If you are using the Ajax option in the form then make sure that you are not caching the Form page more than 24 hours.

Manual reviews don't have an icon by default. You can set one by editing the individual review using the pencil icon.

You should be able to use this setting to only download new reviews. Your last completed scrape needs to be less than 30 days old for this to work. The plugin is also supposed to check for duplicates before adding them to the review list.

Add the !important rule...

span.wppro_badge1_SPAN_13.b3s13 {
font-size: 16px !important;
}

span.wppro_badge1_DIV_12 {
font-size: 16px !important;
}

This should control the font size...

span.wppro_badge1_SPAN_13.b3s13 {

font-size: 16px;

}

span.wppro_badge1_DIV_12 {
font-size: 16px;
}

You can use the ID for the element you want to scroll to in this setting...

You could also do it with an overall badge click like so...

Try creating a new review template from scratch and take all the defaults. See if that one works.
