Cannot select view type

Hello,

When i create a view in Designer, there’s no combo box for view type on the right corner of the dialog.

There are a text box for the view name, a list for selecting the location, a “copy from” button and a text area for the selection formula but no combo for the view type.

I’ve the problem on one database only. I’m manager on it on the ACL.

Have you ever seen that ?

Thanks in advance
