Can't save Workspace customization

I’m trying to customize different views. Right now I’m on the project workspace.
I’m in the project workspace and click “Customize” on the upper right corner, I can add a maximum of 2 charts and customize Shortcuts.

I’m not sure why I cant add more than 2 charts so if I go to “Workspace List” and open up the Project-“myusername”, I can “Add row” and add more charts but I can’t save this document. Why?


I guess there is a setting somewhere to limit to 2 charts only? I would like to have more than that.

upgraded to v14 and it’s much better!
