when the 'manual' action is selected then you could not specify the 'assistant' action later on in the 'end' mode

To reproduce:

- force a way to have the app selecting the "manual" mode when you click on the grraph of the grid
- do this manual action
- load an assistant
- select the "assistant" action types
- make it run "till the end" (with the "end" button)

The "manual" actions overids the "assistant" action
