SLA response time clock don't stop

[ftahoces]

Hello

I have just updated OTRS to 5.0.12 and checking the new version I have realized that
response time counter from SLA doesn't stop when I change the ticket state_type from new to open.

¿Anyone knows what could be the problem?

Thanks in advance

Stopping/suspending SLAs requires additional modules

I have done the same updating to OTRS 5.0.12 in a development envoriment and it woks fine.

Where can I check if I have missing this modules during the installation process?

Thanks

check packagemanager which packages are installed

I have already found where the problem was.

I thought SLA clock stop depended on the change of the ticket state, but the issue was solved when I set the note as note-external when I changed the state from note/decision tab.
