Cleanup of the neighbors chart

[meal]

Hello,

I am running domoticz running on a PI3.
The context is the following:
Version: 2020.2 (build 12501)
Build Hash: 2e2691522-modified
Compile Date: 2020-10-27 15:06:45
dzVents Version: 3.0.15
Python Version: 3.7.3 (default, Jul 25 2020, 13:03:44) [GCC 8.3.0]
openzwave version is 1.6-1392-gb0afd4c6.

I managed to get the zwave network run properly after upgrading from Stretch to Buster os and upgrading domoticz to version 2020.2.

However i have an issue with the neighbors chart.

It displays a link between node 6 and node 2 (see in attached document the extract of the neighbors chart featuring the case)

whereas node doesn't exist any longer in the zwave network configuration.

My objective is to remove that link node 6-->node 2 which should not exist.

I would appreciate If anyone faced the issue before and could advise me on the way to do it.
