W2 Line 18. County listed not where I worked.

Filing taxes for 2018. My spouse works from home 95% of the time and only goes into the office 1 or two times every few weeks. We live in Fayette county.  The W2 on line 18 shows JSMIN (Jessamine county) and NCSLV (Nicholasville KY)

Is this correct? Should it not be Lexington/Fayette since that is technically where she worked?
