What's the problem (or question)?

I want to query 5 records from every table.
Run below command
python sqlmap.py -r r.txt -p pwd --dbms MySQL -D xx --dump --start=1 --stop=10 --threads=5 --technique=B
But sqlmap return 5 records from every table only 5 columns,I think it is a bug. At least it is Anti-intuition.

[16:01:27] [INFO] fetching columns for table 'user' in database 'xxxx' [16:01:27] [INFO] resumed: 25 [16:01:27] [INFO] retrieving the length of query output [16:01:27] [INFO] resumed: 7 [16:01:27] [INFO] resumed: user_id [16:01:27] [INFO] retrieving the length of query output [16:01:27] [INFO] resumed: 4 [16:01:27] [INFO] resumed: type [16:01:27] [INFO] retrieving the length of query output [16:01:27] [INFO] resumed: 5 [16:01:27] [INFO] resumed: email [16:01:27] [INFO] retrieving the length of query output [16:01:27] [INFO] resumed: 3 [16:01:27] [INFO] resumed: pwd [16:01:27] [INFO] retrieving the length of query output [16:01:27] [INFO] resumed: 4 [16:01:27] [INFO] resumed: name [16:01:27] [INFO] fetching entries for table 'user' in database 'xxxx'

Do you have an idea for a solution?

--start and --end shoud be sikp the step of columns detect.

How can we reproduce the issue?
