Migration Job Is Already Running Error

I got enrolled for early access to Relational Migrator

Initiated Sync Job for moving data from SQL Server to MongoDB Atlas
It was taking more than 10+ minutes (6 Billion rows)
Hence, terminated/cancelled the sync job
I then re-initiated the sync job with small table holding 70K rows
It throws below error


I have a feeling, the previous sync job though UI shows as terminated/cancelled, it hasn’t cancelled and hence, UI is not allowing to proceed to initiated my second sync job.

Please advise. Thank you!
