Firewall remote log doesn't contains all

Hello,
I have problem with logging. I am logging TOPIC Firewall into remote log.
One of my rule is block trojans IP:

[admin@R1] > /ip firewall address-list print          
Flags: X - disabled, D - dynamic 
 #   LIST                            ADDRESS                                              CREATION-TIME        TIMEOUT

461   Trojans                         208.91.196.46                                        oct/23/2018 09:40:07
462   Trojans                         199.191.50.73                                        oct/23/2018 09:47:22
[admin@R1] > /ip firewall filter print
Flags: X - disabled, I - invalid, D - dynamic
...shortened
30    ;;; BLOCK TROJANS
      chain=input action=drop src-address-list=Trojans log=no log-prefix="" 

31    chain=forward action=drop src-address-list=Trojans log=no log-prefix=""

In counter we can see 1 packet, so I expect it will be in the remote log(Linux machine):

I went to look into remote log:
*

#cat /var/log/mikrotik-Router1.log | grep 66.240.205.34
...nothing was returned 
#cat /var/log/mikrotik-Router1.log | grep 208.91.196.46
...nothing was returned
#cat /var/log/mikrotik-Router1.log | grep 199.191.50.73
...nothing was returned

Could anybody explain me why it was not sent into the log?
Thank You

Maybe change the log=no to log=yes, so it actually gets written towards a log?

Thank You for the hint…I will try it
