Could this be a bug? Radvd cannot start.

Hi! I have a TrueNAS host, running a PfSense 2.6.0 VM (HW checks out). After completing my IPv6 config (56 prefix from ISP, LAN IFs set to track WAN and get a 64 subnet, RAs set to unmanaged) I try to start radvd from the widget and nothing happens. I then find in the logs:
General log:

So, I found a GUI "bug". I had correctly set the prefix ID's in the "Tracked Interface" for each VLAN, but at the RA page, I mistakenly reinserted the prefix ID in the fields that are for static (full, not delegated) prefixes. Removed the static prefixes and everything now works. GUI should not let you enter static prefixes on a tracked interface, aside from fc00 or fd. And if it does, it should check if they are correct. One of the prefixes was ::1/64.
