Decision table unable to generate rule for row with pattern without constraint

rule "Test_1"
	when
		$factA:FactA(hasSomething == "true")
		$numberOfFactsB: Number(this > 0, this <= 1) from accumulate(FactB(x == 1) from $factA.listOfFactsB,count(1))	
	then
		insert(X);
end

rule "Test_2"
	when
		$factA:FactA(hasSomething == "true")
		$numberOfFactsB: Number(this > 1, this <= 2) from accumulate(FactB(x == 1) from $factA.listOfFactsB,count(1))	
	then
		insert(X);
end

rule "Test_3"
	when
		$factA:FactA()
		$numberOfFactsB: Number(this > 2, this <= 3) from accumulate(FactB(x == 1) from $factA.listOfFactsB,count(1))	
	then

end

rule "Test"
	when
