Advanced DSO Can not find InfoObjects to add

Hi All,

We are having problem adding InfoObjects to our Advanced DSO. We cannot find InfoObjects when searched in Advanced DSO. Please check the screenshots below. We can only see UNIT InfoObjects.

We have developed Advanced DSO before in the same system. It wasn't any problem. We don't know what happened now and we are not able to add objects. Even the DSOs we created before, we can not find InfoObjects.

This was created before. We could add InfoObjects before, but now, we cannot even add InfoObjects to this one either.

Please help.

Thanks.
