Hi, we're just starting with OpenLP. I built an order of worship in one of the stock themes, then created a simple colored theme for the current liturgical season. Now I can't seem to switch the theme. I've attempted to do so in the way that seems appropriate, by choosing the new theme in the dropdown under "service manager". I've even made this theme the default theme under "theme manager". Any idea what I'm doing wrong? I'm running OpenLP 2.4.6 on windows 10.
