I'd like to help. For the fastest and most accurate help, it's important to include technical information. You don't mention which version of Wirecast or what OS you are on which can be any number of Windows or macOS builds.
Give that I can only guess that you're on Wirecast 14.1 and macOS Mojave. This is an issue that will be fixed in an update. If you're on Windows I'm going to need more details.
