In my testing, it does not appear on the list of classes in a 2024 sheet Jumpgate game. It does appear on a Jumpgate 2014 sheet game. My guess is that there is something in the code for the third-party compendium that is not agreeing with the Beacon sheet. You can try contacting the publisher. They likely outsourced the compendium work, so they may be able to contact their service and see what the issue is. There are many, many, many third-party publishers that do show up on the 2024 Character Builder, so hopefully it isn't impossible to fix.
