How can we make checkboxes vertically center align in simple form?

SAPUI5 simple form does not make the checkboxes vertically center align.

Here is the code:

<form:SimpleForm title="{i18n>wizardDateLocation}" minWidth="1024" editable="false" layout="ResponsiveGridLayout">
    <form:content>
        <Label text="{i18n>wholeDay}"/>
        <CheckBox selected="{/IsAllDay}" editable="false"/>
        <Label text="{i18n>date}" visible="{= ${/IsAllDay}}" required="true"/>
        <Text text="{/Start}" visible="{= ${/IsAllDay}}"/>
        <HBox></HBox>
        <Label text="{i18n>from}" visible="{= !${/IsAllDay} }" required="true"/>
        <Text text="{/Start}" visible="{= !${/IsAllDay} }"/>
        <Label text="{i18n>to}" visible="{= !${/IsAllDay} }" required="true"/>
        <Text text="{/End}" visible="{= !${/IsAllDay} }"/>
        <Label text="{i18n>isOnlineMeeting}" required="false"/>
        <CheckBox selected="{/IsOnlineMeeting}" editable="false"/>
        <Label text="{i18n>location}" required="{= !${/IsOnlineMeeting} }"/>
        <Text text="{/LocationName}"/>
        <Label text="{i18n>weblink}" required="{/IsOnlineMeeting}"/>
        <Text text="{/WebLink}"/>
        <Link press="editStepTwo" text="{i18n>edit}"/>
    </form:content>
</form:SimpleForm>

How can I solve this issue?
