An activity appears closed in real work imputation

Hello,

We set up an activity in a project, but since a few days it appears closed in Real work allocation so we can't fill the worked days.
The other activities do appear.
We checked that every project and sub-project were not closed, as well as the users.
We also checked that every project and sub-project were not under construction.
The activity is planned as usual but still we can't enter the worked days.

Please do you know why is this problem happening and how to solve it ?

Thank you.

Bonjour,

Nous avons créé une activité mais depuis quelques jours cette activité apparait "closed" dans les imputations et nous ne pouvons pas imputer les jours passés dessus.
Les autres activités apparaissent normalement.
Nous avons vérifié que le projet et les sous-projets jusqu'à celui contenant l'activité, ainsi que les utilisateurs, ne sont ni clos ni en construction.
Alors même que l'activité est planifiée correctement il est impossible d'imputer les temps passés dessus.

Savez-vous d'où peut provenir ce problème et comment le résoudre ?

Merci.

The connected user wasn't hugo, but the problem is exactly the same from his account. He can't enter any work in the activity because it looks "closed".

Please find attached a screenshot of real work allocation from his point of view.

Well if I display the closed elements, the activity shows up as a closed activity, but it's not. So Hugo can't enter any work because the input fields are grey as if the activity was closed, and it shouldn't, I don't understand why the activity appears in that "closed" state, it's not !
