irc-slack + znc constantly adding new channels

[dmulder]

I paired irc-slack with a znc server, and it's constantly adding new channels to my irc client (and I can see them in the znc settings also). Every time somebody comments in certain channels (such as our help-slack channel), I get a new channel added called +channel-name-0000000000000, where the zeros are some long random number.
I'm guessing this is some kind of bug?

I have the same issue without znc. Just irc-slack and irssi
