Taskmanager Extension: Action Button not visible

Hi again,

I installed the Taskmanager application via extension manager followed instructions but users cannot create new tasks because action buttons not visible. Creating tasks via simply creating a wiki page with template “Task” works. See screenshot below.

I installed it as different user, tried it with various user, checked if I miss some rights but did not see anything. Installed version is 2.5.1 so I have no idea whats wrong.

Any hints?

Thanks
