If the DataGrid has more than 40 rows of data from a database table, it doesn't color all the rows.

Thanks to [krishnaaditya] for the answering how to clear

If I edit one of these items manually in the DataGrid, it seems like the SelectedItem binding on the grid stops working ( RuleListViewModelPropertyChanged in the controller is never called again). But only if I actually change the value of the item in the cell, otherwise SelectedItem keeps working like it should. I have stripped the code of some irrelevant things, so this is basically what I have. First, I have the following DataGrid :
