The 1.88 years is for Mars. 1.94 days is for Gliese, and it does refer to the orbit time around its sun, not its rotation on its axis (which I don't think they're even able to measure at this point).
I brought up Mars to give a comparison to what it would be like if this planet had an orbital period of 1.94 years, so as to show why 1.94 years is unlikely.
