Setting Filter to Is Null results in filter string "column ==" it should be "column== null"
Setting filter to Not Equal set filter string "column == true" should be "column!= true"

Proposed code changes.

else if (column.FilterPropertyType == typeof(bool) || column.FilterPropertyType == typeof(bool?))
{
//Added for is Null Is Not Null
if (columnFilterOperator == FilterOperator.IsNull || columnFilterOperator == FilterOperator.IsNotNull)
{
return $"{property} {linqOperator} null";
}
//
return $"{property} {linqOperator} {value}"; //Changed == to {linqOperator} fixes not equal to
}
