Comment 2 for bug 1788444

The similar approach (universal type of copy alert) would be also needed when creating copy alert at checkin or checkout, renewal screen etc.

There is a blank option in the "Type" field when creating new alert, however, if the blank option has been chosen, copy alert is not applied. If one of the predefined types has been chosen, copy alert works properly.
