InfluxDB - Strange behaviour setting up InfluxDB

Running 0.103.3, and just starting new setup. Trying to setup HA with InfluxDB and Grafana on my Raspberry Pi 4B /w 4GB RAM.

When setting up InfluxDB, I noticed something very strange:

In the Network section I see
2019-12-22 13_31_42-Home Assistant

Host 8086 ???

When I type ‘localhost’ and press save, the field is set to ‘disabled’.
When I type the IP adres of my HA device, only the first octet is displayed ( ‘198’ in my case ).

Is this an error, or should I type another value ?
