Issue Adding IP removes other IPs from Adapter

[Sergio Sánchez]

PRODUCT, VERSION, OPERATING SYSTEM, ARCHITECTURE:

Last version Plesk Onyx Version on Ubuntu 18.04

PROBLEM DESCRIPTION:

Adding an IP from my Subnet under Tools & Settings -> IP Adresses get stuck. After 20 Minutes waiting I tried to reload but cant reach my Server.

Via a rescue mode I could see that in "/etc/netplan/10-plesk.yaml" it has deleted the IP except the last that I added before.

I can confirm the bug. It's a serious one.
Thank you Sergio for pointing me to the relevant file.
