Attributes in database but not shown in magento manage attributes section

[vpatel93]

Hi guys I had recently upgraded to 1.9.2.4 and have a weird bug. I previously added a attribute for products, it is there in the database. Likewise, when I go to edit a product it is correctly shown.

But, when I go over to Catalog -> Attributes -> Manage Attributes, and it is not there in the list. 

Also, it displays correctly in the frontend, I have not errors for it either in system.log or exception.log. 

Any tips on how I could debug this and/or what could be the cause ?

Have you checked that your attribute is assigned to proper attribute set? Please verify and let me know.
