Add a new Access Group: Entities dont appear

I am following the step by step bicycle plataform tutorial.

At page 37, it shows how to create a new access group.

Open the Constraints? tab for the newly created group
7. Click Create? in the Constraints? tab
8. Set Entity Name?: Order

In my case, only the sys, sec and workshop$Cliente appear (attached). The workshop$Order doesnt.

Does anyone can help me? I tried to find what I missed, but without success



i typed ‘orde’ in the field and the option appeared.
