What if an engineering degree is not ABET accredited?

I have applied for master's of science in systems engineering. And I looked at the ABET website and the name of that university is only listed for electrical engineering and computer engineering. This means ABET accredited the BS in EE and its BS in CE program. However, the university does not offer BS in systems engineering and only offers MS in systems engineering. But its systems engineering master's is not accredited by ABET. That means its fake degree? I checked wikipedia article about the university and it says, "it is regionally accredited by the Higher Learning Commission (HLC) and a member of the North Central Association of Colleges and Schools (NCA)". The university name is colorado technical university.
