Feed profile data cannot be retrieved

I am using Kylo version 0.9.1.1. with NiFi 1.6.0 on HDP.
After creating the sample feed from standard data-ingest template and it successfully runs with all columns marked for profiling, when I open Feed details under Feeds Manager and I click on Profile tab nothing shows up and I get an error message that I need to contact kylo administrators.

I checked the kylo-services log and I found the error message below.

The problem is that `category_name.table_name` are quoted together instead of `category_name`.`table_name`, or not using the quotes at all in this case.
