Settings static IP for VPN leads to multiple addresses

I created a VPN connection to my FritzBox. When the connection is UP I receive 192.168.1.200 as IP address.

I set a static IP address ("manual") in NetworkManager GUI:

Now I have two IP addresses:

9: tun0: <POINTOPOINT,MULTICAST,NOARP,UP,LOWER_UP> mtu 1412 qdisc fq_codel state UNKNOWN group default qlen 500
    link/none 
    inet 192.168.1.200/24 brd 192.168.1.255 scope global noprefixroute tun0
       valid_lft forever preferred_lft forever
    inet 192.168.1.201/16 brd 192.168.255.255 scope global noprefixroute tun0
       valid_lft forever preferred_lft forever
    inet6 fe80::45b5:72ab:3b02:275f/64 scope link stable-privacy 
       valid_lft forever preferred_lft forever

What I have to to in order to have only the desired IP address and not the default one?

Here the network configuration file:
