Looking at my gmail account with tb instance on device B, while parked at my usual email account, I see gmail account Inbox and /lxr folder unread number increment when the mail comes in (almost immediately). Then I send a message from my usual address to my gmail address from another tb instance on device A. I set up a filter at google webmail to "apply the label" to /lxr when a message received from email address (my usual address). In my gmail account I have an existing folder/label called /lxr. This is enabled by default since you probably want to user IDLE if your server supports it. (*) IDLE, if supported by server, is enabled in tb with the server setting check box "Allow immediate server notification when new messages arrive" it does not explicitly say "enable idle". Also, information on whether you are using the "get new messages" timer (or get new messages button at the top) and/or IDLE (*) function, that affects how quick new messages are received into tb, might be helpful. Please be a bit more specific with which folders are not updating unread count and how this relates to filtering. Maybe I don't understand what you mean by "server side filter" and how they are being used. So it seems to work without clicking on it. Account B's folder showed 2 when I sent another message with subject "test".

When the message was sent I saw the unread count on account B's (destination) folder show 1 without changing focus from account A. I set up a filter to move a newly received message with subject "test" on account A to a folder on account B. However, I think you are not just concerned with INBOX unread count but for unread messages copied/moved to other folders by the filter function of tb (not sure if this is called "server side" filtering). For non-idle servers the count goes up when request for new messages occurs on 10 minute default timer. With new messages received into several account INBOXes I see the unread count go up almost instantly for servers that support IDLE (a.k.a., push).
