Blog Category and Listing Category Issue

I am using Directorypress 8.3, I am facing issue related to category.

When I am trying to add any category for blog post category (WordPress Post Category), it is giving me page not found error for that category page. However Category for listing (Directorypress Listing Category) is working just fine.

Example :

Blog post category URL : https://www.gicn.in/category/leadership-update/ (This is not working, however I do have blog post assigned to this cateogry)

Listing page category URL : https://www.gicn.in/category/technology/ (This is working perfectly fine)

Need help to resolve this.
