WeltPixel GA4 promotional event tracking

I have enabled  Promotion Tracking On WeltPixel GA4 config, and added suggested 
<a href="#" data-track-promo-id="PROMOID" data-track-promo-name="PROMONAME" data-track-promo-creative="PROMOCREATIVE" data-track-promo-position="PROMOPOSITION" >Content</a>
Into promotional banner view_promotion events working fine but select_promotion event not working, can you please guide me?
