Problem with N-A28 signal

The opening bracket preceding ὀπίσω is missing (= replaced word[s]) and the circle (= omitted word) preceding κύψας erroneously has a 1 beside it. The apparatus itself is correct, though. Here is a screen shot of the verse, as well as a photo of the print version:

Thank you!
