CE U12 - Enter Data Fields - Are the underscores disabled?

In my 30+ years of working in MicroStation I always entered Underscore characters "_" in the text editor for the enter data fields.

In CONNECT Edition this no longer seems to work. Entering underscores in the text editor does not create enter data fields as in past versions. The only way to create new enter data fields is to use Insert Enter Data Field from the text editor pop-up menu. Checking my user prefs the ED Character is set to the underscore character.

Files from previous versions of MicroStation where the underscores were used still work in CONNECT. 

Yes, I know enter data fields are obsolete, but they are still part of many client workflows.

Has entering the underscore character for enter data fields been disabled?
