installed in PHP 7.3
I installed using the English language, I verified in the Extcal installation that this error is happening in the image below, and just press the F5 key and it ends the error, and completes the installation of the module, reinstalled the module and the error continues to occur.

A little mistake happens when editing the data of the start date and end date fields, they overlap the small calendar that appears.
