Multicam Resetting Defaults?

I have installed multicam on my 3B+ and everything has been working great, except one minor thing...every once in a while (ok, at least once per session of logging in to check on things) my "default" camera will default to the secondary camera. So then, when I go into the control tab, the first camera shows the second one, and the second camera...also shows the second one. The only way to fix it is to go into the settings every time and reset the "Stream URL" under "Webcam & Timelapse" from '/webcam2/?action=stream' to '/webcam/?action=stream'. Then I can go back to the tab and easily switch between the two cameras. Is this something anyone else has an issue with?
