Import not working

Hi,
Importing is nog working anymore.
There are 4 events, there of them are imported from:
https://www.eventbrite.be/o/world-trade-center-antwerp-29408851947
But when I try to import:
https://www.eventbrite.be/e/registratie-wtc-academy-opmars-van-e-commerce-door-covid-19-128638187281
Using the ID number of this event. It seems that it is importing and I’m getting no messages, but this event is not imported.
Using:
Import Eventbrite Events version 1.6.1
Event Tickets Plus version 5.1.0.2
Event Tickets version 5.0.3.1

Also using:
The Events Calendar 5.3.0
The Events Calendar Pro 5.2.0

Hope You have a solution
