Import from Nucleus and comment count

Hi. This is my first post here at wordpress forums.

I succesfully migrated my NucleusCMS blog to WordPress, including posts, comments and images.

The only error is that on main page every post appears as with “No comments”, but actually if you go to the post you can see all the comments there. They also appear on the admin area. If you post a new comment on that post, comment count “resets” an appears correctly, with the correct number of comments the entry has.

My idea to correct this was to “spam” my own blog, writing one comment for every post, so i fix all the incorrect “no comments” on every post.

Anybody has an idea on how to easily achieve this? Or has another idea to correct thie comment count problem?

Thanks in advance
