The TAKE_PATIENT_PHOTO_TITTLE key is correctly provided (yes, with the typo in it).
And anyway the symptom is not the one of a missing key, it really displays the whole Angular declaration {{ 'TAKE_PATIENT_PHOTO_TITTLE'|translate }}. A missing key would display the key only.
This does is not reproduce on the demo, and there is no other place where this happens.
Any idea what could cause this?
