Problem Finding Command Bar

I am having a problem location a command bar

I load my 5 command bars from an xcb file and there are two command bars that I wish to delete if the user does not have certain admin privlidges.

I am using the following piece of code to iterate through all the command bars and delete the correct bars.

foreach(XtremeCommandBars.CommandBar myBar in Instance.axCommandBars1) {    if(myBar.BarID == ID.IDR_SUPERADMIN && !isSuperAdmin)        myBar.Delete();    if(myBar.BarID == ID.IDR_ADMINISTRATOR && !isAdmin)        myBar.Delete(); }

Now, for some reason, this foreach loop only loops through four of my command bars.  The IDR_SUPERADMIN bar gets deleted but the IDR_ADMINISTRATOR bar, which most certainly exists, does not seem to be in the list?

Any idea on how this could occur?
