I have the same issue.

The language files are not up to date.
You have 2 solutions:

1.
You can solve this raplidly by yourself:
Go to Extensions > Language Manager > Overrides
In the left column I advise you to filter by " **your language** - Administrator"
Then click NEW and fill in the missing strings with your own text like this:

Language Constant: PLG_CONTENT_EASYSOCIAL_POINTS
Text: Points
For both locations: "checked" (this will replace the missing strings in both the administration and the front end)

Then click save and do the same for all other missing strings.


2.
Second option is to wait for Stackideas to provide an updated file...
