Source & Default Filters: cannot filter more than 4 criteria

Hi,

I'm using expression in "Source & Default Filters" in RecordType.

I can only save expression with 4 criteria but I cannot save it with more than 4.

do you have any suggestion. my code is below:

a!queryLogicalExpression(
operator: "OR",
filters: {
a!queryFilter(field: "year1", operator: "<", value:2021),

a!queryFilter(field: "year2", operator: "<", value:2021),

a!queryFilter(field: "year3", operator: "<", value:2021),

a!queryFilter(field: "year4", operator: "<", value:2021),

a!queryFilter(field: "year5", operator: "<", value:2021),

a!queryFilter(field: "year6", operator: "<", value:2021),

a!queryFilter(field: "year7", operator: "<", value:2021),

}
)
