MetroGrid Control showing class properties that are not explicitly declared as Grid Columns

[SkyEngine-OSP]

I explicitly defined what columns my MetroGrid should show, i then disabled the .AutoGenerateColumns on Load Event, then passed a .DataSource value to the Grid via a method i defined that triggers on button click. However, i noticed that when i assign the IEnumerable to the MetroGrid's .DataSource property, it shows the Class Property that is not defined as a column.

i'm using MetroFramework 1.4.0.0 by the way

Edit: a quick workaround i do with it is, i define that extra column that should not appear, then set its Visibility to Hidden.
