Fullcalendar does not work correctly when creating a SPA application

Wappler version: 5.4.2
Operating system: macOS Monterrey 12.6
Server Model: Php
Database type: none
Hosting type: local

I’m having this problem while creating a SPA application. (with node js it works fine).

The behavior is also strange because if I try to resize the browser the calendar is displayed correctly, I also tried on different browsers but the result is the same.

Expected behavior

Your calendar should look like the picture


Actual behavior

This however is what happens

How to reproduce
Create a file in php or html
Add the calendar component to the page and save
Now select the calendar in the app structure and click on move to include then in the next window click on the content page and save the new file
