WordPress MU

What should have in the following tables:

bad_behavior_log
wpmu_1_postmeta
wpmu_blogs
wpmu_site
wpmu_sitecategories

they were created on the intallation but there's no rows on any of them. Is it how it should be?

well, sorry for this post. I just find out it has the rows, I just didn't know how to 'see' it. (gasp!)
I'm just too new to this.
