the generated excel doesn't start from first row if there are multiple if

[takeAction]

I am using jxls 2.14.0, I have a excel template which looks like following:

A1            A2            A3
${b.a1}     ${b.a2}     ${b.a3}
B1            B2            B3
${b.b1}     ${b.b2}     ${b.b3}
C1            C2           C3
${b.c1}     ${b.c2}     ${b.c3}

it has three parts : A, B and C, each time only one part will be generated.

for A1, I add jx:area(lastCell="C6") jx:if(condition="type == 1", lastCell="C2" )
for ${b.a1}, I add jx:each(items="list" var="b" lastCell="C2")

for B1, I add jx:if(condition="type == 2", lastCell="C4" )
for ${b.b1}, I add jx:each(items="list" var="b" lastCell="C4")

for C1, I add jx:if(condition="type == 3", lastCell="C6" )
for ${b.c1}, I add jx:each(items="list" var="b" lastCell="C6")

if type == 1, then only part A will be generated and it start from first row; if type == 2, then only part B will be generated and it start from first row too.

but for part C, it starts from third row, first row and second row are empty row, why? how to make part C also start from first row?
