Describe the bug
i was able to get the database type = "HSQLDB" and database name = "PUBLIC" by using --current-db, but when i trying to retrive the table/column names further using common-tables/columns, it says that no table(s)/column(s) found.
i have cheated and checked the source code to get the table/column names and comfirmed so of the names that webgoat are using is in the provided common-table(s)/column(s).

To Reproduce

1. Run 'sqlmap -r D:\projects\cyberSecurityProjects\note\injection\SQLInjection(advenced)\requests\register.txt -proxy http://127.0.0.1:8081 --string "please try to register with a different username" -p username_reg' to get database type "HSQLDB 1.7.2"
2. Run 'sqlmap -r D:\projects\cyberSecurityProjects\note\injection\SQLInjection(advenced)\requests\register.txt -proxy http://127.0.0.1:8081 -p username_reg --dbms="HSQLDB" --technique=B -D public --tables --level=5 --risk=3' receives no table(s) found
3. Run 'sqlmap -r D:\projects\cyberSecurityProjects\note\injection\SQLInjection(advenced)\requests\register.txt -proxy http://127.0.0.1:8081 -p username_reg --dbms="HSQLDB" --technique=B -D public -T sql_challenge_users --columns --level=5 --risk=3' receives no column(s) found

Expected behavior
i followed a guide from here: https://pvxs.medium.com/webgoat-sql-injection-advanced-5-20ce63bf4aec
and i expect to get some same or similar results he got.
