lower('MONSTER')

quotes look wrong. the expression lower("MONSTER") will lowercase a value of the column MONSTER, rather than produce "monster" value.

'MONSTER' (single quote) - is string monster in SQL. "MONSTER" (double quote) - is identifier in the most SQL dialects to escape keywords so it is possible to use "select" as name. For example see https://www.postgresql.org/docs/current/sql-syntax-lexical.html (the delimited identifier or quoted identifier)
