ASPxGroup child property editors disabled

Hello,
I am trying the ASPxGroupPropertyEditor in my project. I read the documentation here https://documentation.galaktika-soft.com/xafari/doc_aspx_group_property_editor and have implemented a domain class TestClass as seen in TestClass.txt in the included zip. I am using EF as my ORM but class is non percistent so should be of no importance. Just saying because i will use it with persistent classes too.
I have created the required views in model plus the changes in the TestClass_DetailView as you can see in Model.png. I have also added a navigation item to open the desired detail view using Application.CustomProcessShortcut event in WebModule and creating a dummy object there before opening. The end result is that although the detail view opens in edit mode the child property editors are disabled. The one property outside of the ASPxGroup is behaving ok. See screenshot result.png. Any ideas?

sidenote: including Xafari.Editors module in my application changes all default editors from XAF to xafari one. Can i disable this so i leave XAF defaults and only choose xafari when needed?
