[solved]How to remove a VLAN interface

[#1]

Hello, There is no button to remove/delete a VLAN interface on the System > Network page. Any idea how to remove a VLAN ?

Go within the VLAN and make sure there is not a reference to "Create address object matching subnet" enabled.  If it is enabled, disable it.  Here's a screenshot for reference:

So I was able to delete it, by downloading the FortiGate Configs from Gui and then from notepad search for the VLAN interface , what I found out is somehow the VLAN interface is being used by the GUI dashboard of the forti.
