Prevented SSH SFTP Updater Plugin Updating WordPress

I use SSH SFTP Updater support plugin to do the the updates to my websites, this plugin prevented the WordPress version from being updated, it simply jumped straight to the downloading wordpress page and failed because it was not using the plugin, strangely though doing plugin updates and theme updates worked as normal going to the update plugin scrren to get the SSH password first, it was just the WordPress update that skipped that and failed.
I have removed the MainWP child plugin from my sites and can update there WordPress version again.
