phpStorm is listening to every incoming xDebug connection, why?

I am having a weird issue where an instance of phpStorm is listening to every single income xDebug connection even when I am explicitly saying ignore them. This is a micro services application which mean I have about 7/8 containers running and all of them have xDebug enabled/installed. This is how  the Debug configuration looks like:

And here is the Servers section configuration:

I would expect the IDE to only accept connections from `drm-case-v2` but I am getting incoming connections from other services, ie:

Can't find a source position. Server with name 'drm-case' doesn't exist.

and of course it's telling me to setup such server which I do not want to because in this instace of phpStorm I don't care about that other server. What could be wrong here?

I am using the following phpStorm version with PHP 7.2.x and xDebug 2.9.0:

• PhpStorm 2019.3.1
• Build #PS-193.5662.63, built on December 19, 2019
