Wrong sequence in local BLAST DB

1. Tools --> BLAST --> BLAST make database
2. Select murine.gb as input file
3. Check nucleotide radiobox
4. Set output directory and accept the dialog
   Expected state: the database was created
5. Open murine.gb
6. Analyze --> Query with local BLAST
7. Select the created database and run BLAST
   Current state: there are a few blast result, but the positions of the results are NOT equal to the positions on the murine.
8. Select some big BLAST result
9. Fetch sequences from the local BLAST database
   Current state: the fetched sequence contains extra ~1400 characters at the beginning of the original murine sequence

Find out the reason of that extra symbols and remove them.
