Current behavior:
I'm trying to create a MODAL to use for MULTI-date selection. The calendar modal is presented but all options are ignored, e.g. title, weekstart and pickMode

Expected behavior:
The modal should show the title specified in the options object provided, start the week on the day provided (Monday) and allow the selection of multiple "single" dates

Steps to reproduce:
Related code:
const calOptions = {
pickMode: 'multi',
weekStart: 1,
title: "MULTI"
}
const modal = await this.modalCtrl.create({
component: CalendarModal,
componentProps: { calOptions }
})
await modal.present();
