I am running this search over some records...

let srch = search.create({
	type: context.newRecord.type,
	filters: [
		["internalidnumber", "equalto", context.newRecord.id.toString()],
	],
	columns: [
		search.createColumn("internalid"),
		search.createColumn("line"),
		search.createColumn("account"),
		search.createColumn("memo"),
		search.createColumn("entity"),
		search.createColumn({
			name: "entityid",
			join: "vendor",
		}),
		search.createColumn("tranid"),
		search.createColumn("accounttype"),
		search.createColumn("trandate"),
		search.createColumn("department"),
		search.createColumn("class"),
		search.createColumn("location"),
		search.createColumn("amount"),
		search.createColumn("fxamount"),
		search.createColumn("approvalstatus"),
		search.createColumn("statusref"),
		search.createColumn("posting"),
		search.createColumn("type"),
		search.createColumn("subsidiary"),
		search.createColumn("currency"),
		search.createColumn("quantity"),
	],
});

The weird thing is, the number of the last line increases every time I run this search. It is a UE script, so I edit&save, I get something like

1,2,3

, edit&save again, I get

1,2,4

as line numbers. How could this be?
