BuddyPress.org

Well, I found that in the BP-blogmeta table the blog in question only had one row (last_activity), but not the Name and Description fields, so I added them manually and now they appear.

I have no idea why they were not added in the first place though…

Oh, and he was also missing from the bp_user_blogs table, have added that too and now his profile shows his blog.

Hope this can be useful for others with the same problem,

Cheers
