Import Excel doesn't appear to be working


I’m trying to bring in values from an excel spreadsheet to populate Room parameters with translations and departments (see screenshot below). For some reason, if I run the graph as-is, the excel file won’t even import. If I freeze the “Rooms” and “List.DropItems” nodes, then the excel will import and I can get the rest of the graph to run after unfreezing. I thought maybe the Passthrough node would help since it looks like there’s a sequence issue, but that doesn’t help either. Does anyone know why this might be happening?
