Hi there!
Thanks so much for getting in touch! I’m afraid that we’re not equipped to provide technical support for current plugin users here in our pre-sales forum. We’d be more than happy to assist you at one of the following locations:
For your specific issue here, it may be helpful if you’re able to provide a link or a screencap of an affected Facebook post, as well as a link to the event on your site–this way, we’ll be able to see what data is being imported by Facebook and compare it to the event page’s markup.
Thanks again, and we’ll see you in the forums!
