Problem with D710 Lockout function

[NJ9G]

I'm trying to use the scan-lockout function on a new D710. The manual shows this:

However, when I select a channel and pull up that menu, I don't get a binary on/off option like shown here. Instead, I get something that looks like a free text field, but only lets me enter numbers. So, I could enter 123457 or something like that.

Anyone know what I am doing wrong?

Hmm. After turning the radio off and turning it back on, this problem went away. Not sure what happened.
