Code folding happens even when disabled

In File | Settings | Editor |Code Folding      NONE of the checkboxes are checked.  That has been the case since installation 4 months ago

However:  In the following code it all gets folded every time i go to the file.  So i have to manually unfold them (and occasional other code fragments as well).

    }
    try {
      conn = DB.getConnection(DBFromMR.readProps(conf, conf.get(CurlToS3Job.DB_CONFIG_FILE)));
    } catch (Exception e) {
      throw new RuntimeException("Unable to connect to " + MyJobDB_CONFIG_FILE, e);
    }

Gets folded into one line

So .. how do I permanently disable code folding once and for all?

(note: i had some earlier conversation about this, but this problem occurs in both scala and in java)

I am on 12.0.4 utimate.
