Some Facebook groups won't let me unlike them?

[largepie642]

I'm just going through my facebook likes, and unliking the irrelevant ones, but some won't let me. They say I've already unliked them.
What do I do?

For groups, you can't ''like'' or ''unlike'' them, you can only ''join'' or ''unjoin'' them.
However, with pages, you can ''like'' and ''unlike'' them.

Hope this answers your question.;
