Why do you say that is a problem?  It is designed as such.
Technically, there isn't much reason not to just use a single token,
but the original design was intended to be generic enough to allow one
token per form served (to keep the attacker guessing).  They are
automatically culled when they expire.  You can set more aggressive
culling by setting $max_token_age_days to a small number (1 is fine,
but keep in mind that if someone leaves, for example, a compose form
open for more than one day, then tries to click Send, it will be
rejected because the token expired) in config/config_local.php.
