Registration process leads to recording

Hi

Colleague was trying to register to the webinar planned in more than a week from now. He went thru the registration form, after clicking register, instead of registration confirmation page he was directed to the recording of the webinar from the last year. The registration did not happened, as the colleague was not on the registrants list. When he repeated the process, it went well, confirmation page was shown, he was on the registration list. I was not able to reproduce the issue, my other colleague as well. I had already twice information, that something is not working correctly with the registration process, however for different event. 

Therefore I have the question:

- have any of the community members experienced problems with registration not working correctly?

- have any of the community members experienced situation, in which the registration leads to the recording?

- what can be done to avoid mentioned situations?

Best Regards
