Meeting disappears when re-added

Hello! I am creating and deleting meetings using the API. I do it well. But there is one problem.
If I create a meeting, delete it, and then create it again at the same date and time, it will appear for a second and disappear. Please tell me what is the problem

@romanus.message , I am not familiar with this. Can you please do a screen recording of this?

Thank you!
