How to add "Company Overview" to "About" section of Facebook business page"

Recently I came across this challenge. I was setting up the Facebook Business Page for my employer. Going through the profiles of all competitors, I made note of all the things I must fill in the about section. When I came to set up and optimize the employers Facebook page, I found something was missing. Most important of them was "Company Overview". Then I started to research on how to add the company overview field to about section. Surprisingly, there was no result, including Facebook support, that answered my query. There were many queries and comments on the Facebook help page that were waiting for answers from ages.

Then I thought to do some workaround and figure out the settings. After a lot of workarounds and changes in settings finally I found the the reason why I wasn't able to see the "Company Overview". Actually, It was very simple. As always, everything is hard until its done and easy once it is done. Below are the images that shows how I did it:

This was the setting I saw in the about section. You check the category "Marketing Agency" (Marked in blue) in which the Company Overview and other fields were missing (see it in the below image).

You can see the area of the image encircled in red, there is no Company Overview and few other fields are also missing. Now, below images shows what I did to add the other fields.

I just changed the Category to "Product/Service" from Marketing agency. Take a look at the below image to see what are the fields that appeared that were not here earlier.

Just choose the category that suits your business and also have all the required fields in the About section. I choose the Product/Service because all the business deal with either of two. After all, it is a business page. This small discovery consumed my half day. I hope this article saves someones half day who inputs the same query as mine.
