This last message is normal.  In a triangle configuration at least one port will have to enter blocking state to prevent loops.  Although it should have entered blocking state *before* allowing any data to flow, which might explain the dupe message (some sort of loop occurred?)

Yeah, your IPv4 addrs aren't conflicting, but the "duplicate address detected!" message seems to only pertain to IPv6 addrs, I'd check there.

Are you having any problem besides the messages?  You didn't say anything about pings not working or anything like that.

Also this is really a bridging issue, not a hostap or WDS issue, so it is somewhat off topic here.
