"motion sensor ... was active" notification instead of "motion detected"

Hi all. I have an Aotec Multisensor 5 and an Ecolink Motion sensor. They’ve both been offline for a while (over a year) because they ran out of battery and I was too lazy to go up a ladder and change batteries. My question is: I could swear my SmartThings phone notification used to say “motion detected” but now it says “motion-sensor-name was active” when it detects motion. Is this from a firmware upgrade or something? I would prefer that it notifies with a motion detected message instead of a “was active” message. Thank you for any clarification on this.
