NightBot showing a random emote

Hi, guys!
Lately I have had a little error, it turns out that my Nightbot has received a subscription. So I started editing commands and timers by adding my sub emotes to them;
After updating the commands and timers, I realized that the Nightbot shows in the chat a sub specific emote randomly and without having a predetermined time. PS: I must also say that this sub-emote was the one that I have put the most in my timers and commands, does that have something to do with it?
