Menu order + remove blogpost on home page

I’m using the Shuttle theme (with their featured homepage). I can not change the order of the items on the menu bar. I changed the order of the titels/pages through Cutomizer > Menu’s > Page menu to the right order but when I publish, nothing changes on the menu bar on the site. When I reopen the menu options through the customizer or through the Dashboard (Dashboard > Design > Menu’s) the order in the settings is still the way I changed it.

Concerning the display of the last blogpost on the home page. I searched a couple times through the options in the customizer and tried various things, but I can not remove it… I do not publish blogs so I get the text “Nothing Found Ready to publish your first post? Get started here.” on my homepage.

As I recall (I’m quite new to WordPress and still learning) I did not have these problems a while ago… I recently updated some themes, but unfortunately I do not remember if the Shuttle theme was updated to. Can this may be be a bug in the new update and if so, is there a possibility to rewind the update and go to the previous version?

Finally, from the other topics I saw, I get the idea that de Shuttle team is not that user friendly / good, although I really like the sleek lay out of the home page and I need a 4 column option for the home page. Are there maybe other themes that you would recommend?

Thank you very much!
