Problem with group header in Jasper

I am creating a report using Jasperreports but I need you to only print the group header when a condition is fulfilled, in this case a field has an exact value, the problem is that the printWhenExpression function does not work and it prints all the data even what does not meet the condition

<group name="Group1">
    <groupExpression><![CDATA[$F{CEQUIPOPADRE} + $F{CEQUIPO}]]></groupExpression>
    <groupHeader>
        <band height="16">
            <printWhenExpression><![CDATA[$F{CEQUIPO_COMP}.equals("C")]]></printWhenExpression>
            <textField isBlankWhenNull="true">
                <reportElement x="131" y="0" width="118" height="16" forecolor="#080000" uuid="18170f7b-0772-44a9-82f1-0428c85695f5"/>
                <textElement textAlignment="Left">
                    <font fontName="Times New Roman" size="12" isBold="false" isItalic="false" isUnderline="false"/>
                </textElement>
                <textFieldExpression><![CDATA[$F{CEQUIPO}]]></textFieldExpression>
            </textField>
            <textField isBlankWhenNull="true">
                <reportElement x="2" y="0" width="127" height="16" forecolor="#080000" uuid="dcb89d30-436f-4481-a649-36189d9ffbb6"/>
                <textElement textAlignment="Left">
                    <font fontName="Times New Roman" size="12" isBold="true" isItalic="false" isUnderline="false"/>
                </textElement>
                <textFieldExpression><![CDATA[$F{CEQUIPOPADRE}]]></textFieldExpression>
            </textField>
            <textField isBlankWhenNull="true">
                <reportElement x="253" y="0" width="499" height="16" forecolor="#080000" uuid="bf2a1e61-4381-4e4b-9ce0-865ff89a3d57"/>
                <textElement textAlignment="Left">
                    <font fontName="Times New Roman" size="12" isBold="true" isItalic="false" isUnderline="false"/>
                </textElement>
                <textFieldExpression><![CDATA[$F{CDESCRIPCIONEQUIPO}]]></textFieldExpression>
            </textField>
        </band>
    </groupHeader>
    <groupFooter>
        <band height="1"/>
    </groupFooter>
</group>
