Hidden Blocks - Basic Form Elements Text

Hi,

I'm seeing a strange issue in my CMS forms.

We have a good number of forms, and a good number of elements shared across forms (Common elements)

But some fields show as it's located/placed in "For This Form" (Local content) also used in many forms. below is the screenshot for better understanding. 

At the same time the element is not present in the "For This Form" folder, screenshot reference as below.

It's highly confusing !.. or Am I missing something. ?

If any has an idea about this, please help me to figure out the issue..

Thank you,

Hari
