unexpected behaviour of rndc dnstap -roll

I am generating dnstap files using bind and regularly roll them using
'rndc dnstap -roll [number]'. The way I understand the documentation is
that there should be max [number] old dnstap files after executing this
command but what actually happens is that all files are being kept so
that I have to remove the old ones myself.
This is what the documentation says:
dnstap ( -reopen | -roll [number] )
... If number is specified, then the number of backup log files is
limited to that number.
Am I missing something here? Is the behaviour that I'm observing the
expected one? The logs don't tell me much and I couldn't find any hints
about this on the Internet. Thanks for any help!
