Buttons not working in any themes Galaxy S7 edge

Have tried to use live theme buttons on multiple free and paid themes and noneven have worked for me. Can you please address this? Thanks

Tap to Wallpaper must be supported by the Launcher, in some case (es in Lightning Launcher) you need to go into the settings and map something to the Command / Secondary Command action. In case of issues please contact Launcher support. In order to have touch actions to work in the bottom area of your launcher you need to have the app dock hidden, this is not available in all Launchers.
