Updating the config in <jenkins_url>/gerrit-trigger/server/<name>/ do not take effect.

I have checked the box "Vote patch sets with same topic" in this config but the trigger still doesn't seem to vote for all changes in the topic.

Expected behavior:
From the config "If this option is enabled, build notifications and votes will be sent to all patch sets within a Gerrit topic."

Actual behavior:
Notifications and votes are not sent to all changes in a topic.

Steps to reproduce.
 * Create an instance of a Gerrit trigger <jenkins_rul>/gerrit-trigger/.
 * Fill in the required fields name, hostname, frontend url, ssh-port, username, ssh-key, ssh Keyfile Password, Gerrit HTTP username and Gerrit HTTP Password.

• Check boxes Enable Code-Review, Enable Verified and finally "Vote patch sets with same topic".
• Create a job using the Gerrit trigger that was just created.
• Create two commits.
• Push each of them to Gerrit review with <remote> HEAD:refs/for/<branch> -o topic=<topic>

After running these steps I have seen that the messages and votes from the second commit does not appear on the first commit even though they are in the same topic.
I have also seen that changes to certain fields in the config, <jenkins_url>/gerrit-trigger/server/<name>/, aren't applied, such as Build Current Patches Only. These issues may be related.
