Students unable to program robots in own challenge

Hi all,

I noticed that this forum is active (while the English version is unactive), so I'm posting my question here. You can answer in French, google does a great job of translating it to English.

I have created an own challenge, and my students who open the challenge cannot program the robot anymore after the first attempt.
So on this picture, I've managed to drag the start block in the programming field, and after I pressed play and stop again, I never get the scratch blocks back. I'm also not able to delete the block and switch to python code.



Should I add something to the manager in order that this is possible?

Thanks!

Bonjour!

Laurent was so nice to help me out, I've initialized my manager incorrectly.

For the people just starting to make their own challenges, this is correct order of starting, resetting and stopping robots (in my case Thymio):



Good luck!
Mirjam
