Thanks for reporting the bugs, we appreciate. Here are our comments:
#1 Please check the “Add new after publishing” box on the edit screen – Added in v2.3.2, the “Add new after publishing” checkbox redirects you to a new post page after adding a post, instead of leaving you on the edit page. This option sets the default state for this checkbox. We tested the functionality locally and it’s working for us.
#2 We will look into this. Just curious – any chance you have overwritten the the theme files? Please let us know.
