Hidden enterable pdf form fields in acrobat reader

Hello everyone,
 
When opening a PDF with Acrobat reader created with Jaspersoft studio, the editable fields are hidden.

The values ​​of the fields appear if I uncheck the preferences/forms/Display color option when passing over the fields of Acrobat Reader.

<reportElement positionType="Float" mode="Opaque" x="201" y="190" width="150" height="20" forecolor="#000000" backcolor="#FFFFFF" uuid="91dc344b-c21a-4ece-a3dd-31f5ed7c853c">

<property name="net.sf.jasperreports.export.pdf.field.type" value="Text"/>

<property name="net.sf.jasperreports.export.pdf.field.text.multiline" value="false"/>

<property name="net.sf.jasperreports.print.keep.full.text" value="true"/>

<property name="com.jaspersoft.studio.unit.leftIndent" value="px"/>

<property name="com.jaspersoft.studio.unit.rightIndent" value="px"/>

</reportElement>

How do I make the value of all editable fields appear by default ?
 
Thank you in advance for your help.
