WBS Series break up after setting deletion flag

Hi Experts,

I was having WBS levels at 1 and 2. I have set the deletion flag at one of my level 2 WBS. Now, the WBS has disappeared. Now, when I am creating new WBS it is skipping the series like for an example:-

I was having WBS

WBS     A

WBS     A.1

WBS     A.2 - Deletion Flag set

Now, I am creating new WBS, I think system should allow me to create WBS with A.2 but it is giving number A.3

I want to know is this is standard behavior or is there any other alternative so that I could use the same A.2 number for new WBS

Please suggest.

Thanks,
