Problem with EasySocial button labels

Hi
I'm new to Joommla and EasySocial.

I've installed EasySocial on a Bitnami-Google Cloud Platform instance of Joomla 3.6.2.

THe installation seems to have went well, except for the labels for buttons and links relating to EasySocial functions.

I.e., instead of just saying "Share", the share button is labeled as "COM_EASYSOCIAL_STORY_SHARE"

(Also, see the attached screenshot)

Maybe I've missed a configuration step?


Thanks,
aaron
