Hi, attached a test project that shows partially the bug I'm experiencing.
When marking the first and second checkbox, then making a search, then deleting the search, only the first checkbox remains checked. That's all I can reproduce on a small project, but this is bigger, it sometimes duplicates the 'Name' field into the second field. And sometimes I do a filter and it gives 2 items duplicated insted of one.
Seems that there's a problem with filtering the grid...
