Channel limitation - Teams free

Hello. I've created a community on Teams free and I've reached a limitation of 5 channels. Everywhere site I've searched mentions a much larger limit (with the smallest one being 10 channels), but after only 5 I'm getting the message that I've reached the limit. Is this a new (lower) limit implemented recently for the free version, or do I have something configured wrong in the free version?

I've searched in every setting and can't find anything that would cause the channels to be limited to only 5. Anyone knows?
