Bug report—macOS keyboard shortcut new bookmark
To bookmark text, drag to select it. The selected text becomes the label of the new bookmark ONLY if you use the mouse—using the keyboard shortcut Ctrl-B creates a bookmark with a blank name.

We tried the same and its working fine. We are able to create a label using ctrl+B.
Can you please share the Acrobat version and exact steps you are performing.
