Hi, my first post here, if i posted in the wrong category or forgot something please do tell. 

What i want?
I want to use the same Sort & filter functionalities in my C# WinForms application that Excel uses.

What did i try?
I installed the NuGet Package Advanced DatagridView (ADGV) and did what this tutorial vid on Youtube instructed me to do:

 (Not allowed to post links yet)

What is going wrong?
Well ADGV works fine except for the Filter, let's take the following data:

When i press a filter i get a neat little menu like this:

When i check a box, let's say TEST or example

It removes Test from the column (ColumnF), "Yaay!" you would think right? well no, because here comes the issue, it also removes it from the menu:

So i can't Check it again to have it show again :|

Sure Clear Filters works, but if i have like 5 filters active and i need to remove only one it becomes a hassle :|

I did exactly what that guy in the vid did, but he doesn't seem to have any issues... does anyone know what might be wrong? Could anyone help me?
