shim-br0 networs duplicate address with host

Just noticed my Unifi DHCP is complaing about a duplicate IP address.

When looking at ip a on my server, I see its IP twice listed: 

12: shim-br0@br0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
    link/ether 56:87:88:2c:2a:07 brd ff:ff:ff:ff:ff:ff
    inet 192.168.32.20/32 scope global shim-br0
       valid_lft forever preferred_lft forever
    inet6 fd01:86af:55ec:40d9:5487:88ff:fe2c:2a07/64 scope global dynamic mngtmpaddr
       valid_lft 1654sec preferred_lft 1654sec
    inet6 fe80::5487:88ff:fe2c:2a07/64 scope link

and 

8: br0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
    link/ether 00:0a:cd:3e:64:a4 brd ff:ff:ff:ff:ff:ff
    inet 192.168.32.20/24 scope global br0
       valid_lft forever preferred_lft forever

 

My docker settings are like this:

Routing table:

Why does the shim-br0 use the same IP as the host itself?
