'monitoring' keyword as table name

Hi all

We're on 8.1.5 and external developers added a new table named 'monitoring' to our database. Now, We're facing a phenomenon where we don't have an explanation:

SQL> select sum(m.visits_today) from monitoring m;

SUM(M.VISITS_TODAY)

            2588115

SQL> select sum(m.visits_total) from monitoring m;

SUM(M.VISITS_TOTAL)

           13415014

SQL> select sum(m.visits_today + m.visits_today) from monitoring m;

SUM(M.VISITS_TODAY+M.VISITS_TODAY)

                           5176252

Anyone with an explanation?
TIA
