2 of my units show that file 2018yearlyreport.htm as your attached they also have climatedatayearout1999.html next to it in the folder also with no data in, the other unit is ok but no climatedatayearout1999.html showing not sure why its there as the correct file climatedatayearout2018.html was created 00:11 on 1/1/19 and has data in.
As the 2018yearlyreport.htm and climatedatayearout1999.html appear to both be created at 23:55 it my be linked.
