[Therion] Therion 5.3.16 using raft symbol both for rafts and raft cones

Hi, I'm producing PDFs of a map with raft cones but Therion is preparing a PDF with raft (calcite raft) symbols instead. I tried changing the points to raft but the rendering doesn't change. I'm using Ubuntu Therion 5.3.16. How can I further debug this issue? Regards, Rodrigo Severo
