change log level of application not work

[SBKK]

i am using dlt-control to change some app log level

i have
a app registed as "P1" with 1 context
and a app registered as "S1" with 3 context

i want S1's 3 context to switch to log_level 2

dlt-control -a S1 -l 2 localhost
this not work :
apid : P1 ctid: xxx0
apid : S1 ctid: xxx1
apid : S1 ctid: xxx2
apid : S1 ctid: xxx3

if i change "S1" to "O1", this work :
dlt-control -a O1 -l 2 localhost
apid : O1 ctid: xxx1
apid : O1 ctid: xxx2
apid : O1 ctid: xxx3
apid : P1 ctid: xxx0

in the code src/daemon/dlt_daemon_client.c: dlt_daemon_find_multiple_context_and_send_log_level

looks like with app_flag == 1, if not match, it just break ?
since the contexts are sorted，so S > P not work, and O < P work

Can you please enable log of dlt-daemon, reproduce and share with me (dlt.log file)?
How to enable dlt-daemon log (via dlt.conf file)

• LoggingMode =2
• LoggingLevel = 7
• LoggingFilename = /tmp/dlt.log
