New telephone encounter Reason not showing up in drop down

Noob question here. I’m kind of embarrassed! Last week I added a new “Reason” under Admin > Notes > Tel Enc Reasons. And naturally it doesn’t show up in the drop down list when we you open a new telephone encounter. I went back into Admin and confirmed that it’s there and - sure enough - it’s sitting pretty right in the middle of every other Reason in the list. But it doesn’t show up in a new telephone encounter. I’m about to pull my hair out. Am I missing something? Thanks!
