There was no issue. It was a silly mistake from my end. I had earlier confused them by sending in IQAS ECA through CSE after reading a case got rejected because WES did not mention both diplomas in the summary. Hence the person did not qualify for two or more certificates. My WES ECA summary also only mentioned one degree. So I panicked and sent them IQAS ECA and asked them to consider it as additional information that I do qualify for two or more certificates. So IRCC reacted to my initial CSE and asked for WES ECA for confirmation.
However, later it turned out that WES only mentions highest qualification in the summary so my WES ECA was in fact correct and I panicked for no reason
IRCC later confirmed this too when they accepted my WES ECA
