low temp alert and return to normal temp alerts

[NWGale]

when i look at my messages sometimes only the return to temp alerts show and not the low temp warning, while other times the low temps do show.  am i doing something wrong or is this a bug?

also sometimes the date and times show on the messages and other times they dont!!

I’m having the same issue. No date or time showing when the temperature returned to normal. 
my best has done this three times this week and I don’t know why it stops heating the house
