Difference between ABC::CalcView and _SYS_BIC.ABC/CalcView

Built a graphical CalcView in studio, activated it. (ABC is my package name)

Then went to the reporting tools (ex: Tableau) and tried to connect to the above mentioned CalcView.

Picked schema _SYS_BIC and then searched for the CalcView that I activated.

Saw two results:

1)_SYS_BIC.ABC/CalcView

2) ABC::CalcView

I know we should pick the 1st one (the one with _SYS_BIC) as all the activated column views (in fact all activated objects) reside here in _SYS_BIC schema.

but what I am curious about is the second result ..the one with :: in it (double colons)

What is it? Where is this coming from? Is this the design version of the view?

Any help is greatly appreciated and thanks in advance!
