Catalog recovery tape data base backup exec

good morning

I'm testing in a secondary recovery backup exec 2014 server (SP1)

We have cataloged a tape and I was able to retrieve information without problems

After that we've initialized the database backup exec with the option Drop the existing database and reload from backup. "

When attempting to catalog the same tape again to continue testing not see any of the backups that were seen previously

You know that it may be?

Thanks in advance
