I'm trying to add graphs to devices, but according to the docs I should have a dropdown to select the graph type under the template list. I'm not getting this dropdown list. I feel like there's something broken in Cacti, but the only things I can find are "Update PHP!" and "It's a training issue!" - It's a fresh machine, and I'm following the documentation as best I can. See: https://docs.cacti.net/Graph-a-Single-SNMP-OID.md - first image shows "Create (Select a graph type to create)" dropdown at the bottom. That's what's missing.
