Thanks for the output, that explains why it is not showing you.
You have the following command to disable syslog# 106100 which is what you are after:
no logging message 106100
To reenable logging of syslog# 106100:
logging message 106100
Secondly, your ASDM is only configured with "warnings" (level 4) syslog, while your access-list log is logged under "informational" (level 6), that's why it's not showing up as well. Please modify the logging level for your ASDM to level 6 (informational) as follows:
logging asdm informational
Hope that helps.
