Deletion for SSCUI entries are only possible when the coding mask is just created and "No projects are created with this coding mask key or pattern yet".
Even if there is 1 project which exists then that project becomes not editable.
Before removing the coding mask please ensure that there are no projects created with this coding mask, as after the deletion these will become unreadable.
