Using option "category task is mandatory" the statut changing of the task is not allowed with the checkbox version 2.7

[gpiera]

Hi,
When i use the option "category task is mandatory" "category task is mandatory" the statut changing of the task is not allowed with the checkbox in version 2.7.

The right "update all task" is allowed in the profil user.

Other issue when i add a news task with a category i have an error message

When i save the ticket

After a new test ,when we have the behavior if the duration is use in the task

Thanks
