How to fix this error?

When a new entity type is inserted, it is placed over an existing
entity type or specialization category. The object that it covers is,
therefore, not visible after the new entity type is saved.
After the entity type has been inserted, the objects can be separated
again. To do so, move the visible entity type using the left mouse
button.
