One week ago I picked a sub Assignment only to find the same getting cancelled just a day before the start date. The same assignment was again posted after a minute of cancellation. However the system won't let me accept this assignment again and I got the following message.

"A substitute called by the system is currently reviewing this job. If they do not accept this job, it will be made available. Please check back"

Is this a case of school cancelling the job intentionally and posting it again for one of their favourite sub or am I overthinking?
