Contact group lost after logout

I’m running spark 2.6.3 and openfire 3.7.1 and using the database that comes with it HSQL 1.8. When anyone logs in they can make contact groups but when they log out and back in the groups are gone. I do have three shared groups and they work.

If I look at the spark logs I keep getting

org.jivessoftware.spark.util.log log error

Severe:

Thank you,
