NO RFE but --> Response to USCIS's request for evidence was received

[donrad64]

Hi everyone,
Today I received an email from USCIS saying that Response to USCIS's request for evidence was received. I have NOT received RFE from USCIS let alone answering one that they have received my answer on Aug 16, 2019.
Any idea what's going on?

Also, it says "the case is ready to be scheduled for interview July 26, 2019"

Thanks
