Static Home Page/Blog Page option breaks on upgrade to existing

had existing site on 4.2.7 and older tempera, however on upgrading, and installing the new configuration plugin for theme settings, the normal configuration option for Static homepage/blog page ceases to work correctly for us. The presentation page comes back only once you change the setting to “Front page displays – Your latest posts”
