Different shaddah in different quran manuscripts

In quran.com in [surah Nur ayat 33](https://quran.com/24:33) the word "yukrihhhunna": >يُكْرِههُّنَّ has a shaddah on the second H/ھ. However, I saw a manuscript from a friend of mine that has no shaddah on H/ھ. How could this be? **update** You can see a difference sample in this website, which is one of the well-known resources in Iran: https://wiki.ahlolbait.com/%D8%A2%DB%8C%D9%87_33_%D8%B3%D9%88%D8%B1%D9%87_%D9%86%D9%88%D8%B1
