Can't edit or create condition for checkbox

Version: 3.0.4.2105

In the IIS Bindings section, I can no longer check the empty box to the right of the “enabled” checkbox to have a variable or expression provide that value.

If I click the box, nothing happens. Tried in Chrome and Firefox.

It looks like this might have been resolved in 3.0.5, but I’m not completed sure if this specific issue was fixed:

Upgrading resolved my issue.
