When I right click on an empty section in Dolphin file manager, and select "Link to Device" sub-menu, it appears that there is no template there, and the menu entry is still there. It is clear that no template for Link to Device entry is installed, but the problem is even though no template is configured, the sub-menu entry is just there. This problem is also re-producible in KDE Neon and openSUSE Tumbleweed.
