Scheduler not repeating events

I am sending back to the scheduler everything I got from the onEventSave data object, but when I send it back into the scheduler, the scheduler just shows it as an ordinary event - not a repeating event… what am I missing?
I am including this in my cshtml file

this is the object I am sending to the scheduler - why doesn’t it repeat the event? why does it show up as just an ordinary event? … sp=sharing

please attach a demo project where we could reproduce the error, otherwise it’s hard to tell the possible reason
