Subview Topics All ?

[Muderiz1]

Hi all,
I got a stupid situation in my model-driven app. When I am clicking on Subarea "Assistants" on the left side , I am getting some stupid subview under system view "Active assistants" , as You can see on this picture below :

Why I am getting this view and how can go back on my regular system view like that :

What did I wrong and how to get a "proper" system view ? 

Many thanks 
Edin

Hi @Muderiz1,

It's a bit difficult to see without a full screenshot of the impacted view. By any chance did you select any option in the Group By? It looks like it's applied a grouping on Last Name or something. Try clearing the group by if that is the case.

Hi Chris,
thank You for Your message. I am trying to find out " Group by" in a new Platform Solution Maker, but  no where to se "Group by"... As You know, there are only "Filter" and "Sort" options available. Luckily, I have found "Group by" in Classic view , but I am getting error message :

When I click on Dont send, it comes out that nothing is possible to do whatever I try to do :

I can not click on "Filter criteria ( where actually Group by, Ungroup and other commands are) nor on Columns or any other click is possible ...

I tried to delete Active Assistants View in View Designer and App Designer and then in Solution explorer, then I made it again from scratch . but still the same error happen and still the view in App is like before.

I do not want to delete Assistants entity, but it seems that I will have to do that...Any advice , please ? 
Many thanks , Edin Muderizovic
