Swarm: agents do not participate on "Processing Mappings"

Hello everyone. I would like to ask a question about my problem with distributing of lightbuilding using multiple stations through Swarm agent.
The situation is here:
Coordinator NAME: MAK; win 10 latest updates, Swarm agent from UE 4.11.2, Swarm Coordinator from UE 4.11.2
Remote_agent NAME: JAN-PC; win 10 latest updates, Swarm agent from UE 4.10.4

The problem is that Remote_agent JAN-PC Collected emited photons, but did not processed them.
Here you can see settings of SA:

Same things happened when Coordinator MAK used 4.10.4 Swarm agent and Swarm coordinator as well as Remote agent JAN-PC.

Scene settings:

I read posts like there is a high lightmapped mesh in the scene, so as you can see, there are few meshes with 256 lightmap resolution. Here are my world settings:

So if anybone has, or had, the same issue and found a solution, I would be thankfull. Thanks for your time (if read).

Bump. Same thing here. 4.14.3

any updates on this?
