Missing sorting problems on HackerRank website's dashboard

[rasik210]

I've found one issue on HackerRank website and want to validate if other users are also facing this. If you see the problems listed in this repository under Sorting section, there are 19 problems in all as below:

• Intro to Tutorial Challenges
• Insertion Sort - Part 1
  .....
  .....
  ....
• Lily's Homework
• Big Sorting

But if I go to Dashboard > Algorithms > Sorting section under my HackerRank profile I see only 15 problems. Below problems which are specifically related to sorting are missing:

• Quicksort 2 - Sorting
• Quicksort In-Place
• Running Time of Quicksort
• Counting Sort 3

Although I can click the link to these problems present in readme to navigate to hackerrank but in the bread-crumb menu at the top it doesn't show any hierarchy which means it is nor part of sorting section.

So any user who is following the practice dashboard will not get to know about these four problems that they also exist. I came to know about them from this GitHub repository.

I just want to validate with other users if they are also facing the same issue or not? I've raised an issue with Hacker rank support team as well but they are saying this is my profile specific issue. You can comment on this thread and let me know.
