I am running into the same issue as we move away from being primarily Windows focused in order to catch security vulnerabilities on non-Windows assets. As we migrate from SNMP scanning to SSH scanning for Linux (as recommended) we are seeing this issues, and I've been unable to find any way to remove the old, extraneous data.
I find the lack of transparency into the scanning history of a node inconsistent and frustrating. It would be helpful to have the "Scanning History" tab show up for all nodes, and it would be equally helpful to be able to disable certain scanning protocols/methods on at the node level.
