Hi @HUMBERTO_V , I know this very well.
I have lost some badge too, due to the migration. This happens because with the migration not all posts were moved in the new Connect. Consequently, all the likes received for the topics that were not migrated are now lost. Same for the solutions, that weren’t considered during the migration. I’ve lost all my solutionist badges.
Of course this is just a technical explanation, but I would like to consider this as an opportunity to write more. I am sure you will get them back in a short time.
Hugs

P.S.: I want to inform you that I am moving your post in a more appropriate section: Google Maps tips & tricks - Local Guides Connect
