Cause : SendDlgItemMessageW(hwndDlg, IDC_DESCRIPTION, WM_SETTEXT, 0, (LPARAM)pItem->szHelp); is only call on LVN_ITEMCHANGING. https://git.reactos.org/?p=reactos.git;a=blob;f=dll/shellext/netshell/lanconnectui.cpp;hb=bdae8cf96695fe1e7302da46227052d0faf822ef#l348 

Therefore, if NO item is there, the default text from the ressource file is displayed.

Either IDC_DESCRIPTION shall be set to "" in all lang (saves size) OR SendDlgItemMessageW to be sent with empty text on initialization of the page with processing of WM_INITDIALOG here : https://git.reactos.org/?p=reactos.git;a=blob;f=dll/shellext/netshell/lanconnectui.cpp;hb=bdae8cf96695fe1e7302da46227052d0faf822ef#l264
