Bug: sql: concat instead of arithmatic operation

Question

Under
sql > filtering > custom columns
both 2/3 and 3/3 are on concatination.
3/3 should on arithmatic operations

Answer 1

if you have numbers stored as a string and you attempt mathematical operations, these are overloaded operator for concatenation on purpose.
The strings probably need CAST to make them numbers in addition to the mathematical equation

Answer 2

do you mean you agree, if so how to let author know to fix it?
