My Short links are not working

Hi,
My short links don’t seem to be working. They are taking me to my last site URL. Can you help me please?

This is an example of the short link that is not working: https://wp.me/p4Epz3-qg
It should take you to this : https://www.fresh-sweet-sexy.net/fss-promotions-pres-dj-mrcspssr-10th-birthday-mix-fss-promo/

Thanks!
