In the attached file, segments 9 and 11 are rendered (correctly) as non-translatable, based on phase-name value. However, you can still double-click on the targets and edit them normally.
There are currently two separate notions of 'transatablity' in Ocelot:
Segments that are not translatable (ie, translate="no"), which may be hidden from the UI as a result of Marta's work in commit 683044873
Segments that are not "editable" due to phase. These appear grey but are still visible (and currently editable, although they shouldn't be).
I think it's an open question whether we should unify these behaviors – ie, make segments that aren't editable due to phase subject to the translatability visibility toggle.
