Thank you for contacting Toolset support. Please delete Toolset plugin from WordPress dashboard (make sure there is no Types related folder, for example “Access” exists in your FTP, if you see any Types folders in FTP then please delete it) and re-install it again from Commercial Tab in WordPress Dashboard.
Very odd but when I went back into WP Admin to delete the plugins as you suggested, the update messages were now saying that updates were available and when I clicked to update they did without error
