Eligibility for Express Entry


I recently completed the online PR application and I got a response saying that I am not eligible for Express Entry stating a very generic response (I have attached a screenshot of the response) . So I still don’t understand what the specific reason why I am not eligible.

I have about 7 years of software engineer experience in the USA and so does my spouse. My IELTS scores are as follows:

Listening: 8.0
Reading: 8.5
Writing: 8.0
Speaking: 7.0

Overall : 8.0

My spouse also has about 10 years Software engineering experience, but has not taken the IELTS test.
