Disable Send A File

We are using the client control on the server and using spark 2.5.8. I have file transfer disabled on the server and it does disable it, but when looking at my contact list, right-click a user and I have the send a file option, it doesn’t work. but its a little confusing. when I open a chat window for a user the file transfer button is missing.

it still works but I would think if the client control can make the button disappear it should be able to make the menu change also.
