Calendar display bug only in ios theme

Hello I have this bug only in calendar / sheet modal
It looks as expected in md theme but in ios theme there is

I haven’t change any related css and use simple default calendar like this

<li class="item-content item-input item-input-outline">
                            <div class="item-inner">
                                <div class="item-input-wrap">
                                    <input type="text" name="date" readonly="readonly" class="calendar" />

var calendar = app.calendar.create({
        inputEl: '.calendar',
        closeOnSelect: true,
        value: [new Date()],
        dateFormat: 'dd/mm/yyyy',

Am I missing something ?
Any idea @nolimits4web ?
