Click the Quick access button (the blue star) at the top. In the right pane or the folder view, select the FTP link, press CTRL and select another item that you want to Unpin. Multi-selecting items (FTP & a normal pinned folder) and right-clicking would show the context menu options correctly. Click Unpin from Quick access. For instance, you can Pin a test folder to Quick access, and then remove the FTP and test folder both together.
Esta é a única correção que funcionou para mim e, possivelmente, a mais fácil!
