Actually, this looks completely normal (except for the "prefixlen 64" for the DHCPv6-assigned address, something which was recently fixed in NM). The 2001:db8:dead:beef:20c:f1ff:fed9:97b4 one is the permanent EUI-64-derived address obtained through SLAAC, and the others are privacy addresses. Your OS will probably generate a new one every 24 hours. However, the old ones will remain valid for quite some time before they are removed, so it is normal to see them accumulate up until a certain point. You should look for a tool which tells you the remaining valid lifetime for each individual address. On Linux, this would be "ip -6 address list", but I guess you're running something else.
