### Bug Description

With commit #f8415ed regions on our server cannot be entered, when there's "notify-enter: false" in the region file. (We had one region where notify-enter was enabled years ago and disabled later, a pretty rare case). This also happens to op'ed players.
Setting "notify-enter: true" or removing the "notify-enter: false" entry from the region file completely makes it accessable again.

### Expected Behavior

the config entry "notify-enter: false" for a region does not affect entry to the region.

### Reproduction Steps

1. /rg flag freefarm notify-enter true
2. /rg flag freefarm notify-enter false
3. (trying to enter the region bounces the player back)
4. /rg flag freefarm notify-enter true
5. (region is can be entered again)
