At the moment it is random whether the filtersettings are visible or hidden, when visiting the serverbrowser.
Would it be possible for you to make a setting, whether they should be visible or hidden by default?
I just tried disabling the addon, and without it, if I choose to show the filters, they stay that way.
I don't know what part of the addon that is causing this, but a fix would be great.
This is a bit annoying, i know. But a fix for that should be implemented by battlelog itself.
I tried in the past some fixes for that issue, but non where good enough and make problems at another place.
