Program name starting with " ! "

Hi ABAPers !

For some unknown reasons, while working on the development of a custom program called "ZVER0221_V2", at some point in my development, the Workbench stared asking me ( almost everytime I save a program and/or and include related to this main program ) to select to which main program the object I'm about to save in linked to. The option it gives me are:

!VER0221_V2

ZVER0221_V2

I don't understand why its asking me that... where this !VER0221_V2 is coming from ??&**?

I'm able to display this !VER0221_V2 program and it shows itself as "active". When I try to edit it, I get the following message:

No TADIR entry found for ABAP !VER0221_V2

Can anyone tell me where this program might come from and how can I get rid of it... !!!

Thanks in advance.
