Flow variable changes by itself

I made a flow that has Alexa tell my son when to do certain things in the morning to get ready for school. It also checks a Google calendar to see if it is a “No School” day. If it’s a no school day, Alexa will say nothing. I also have a flow.snowday variable. If I send a “Snow day” or “no school” message to my telegram bot, it also will not let Alexa speak. In testing, everything works as it should. The problem is sometimes the flow.snowday somehow changes and blocks Alexa from speaking when she should. I don’t know what is causing it to change. I set an inject node to reset the flow.snowday variable and it will then allow the messages to go through. Then at some point, could be days later, the variable changes. I don’t know if it has to do when I reboot HA or not.

I replaced the telegram receiver node with an inject node and named it “Telegram Receiver”. I wasn’t sure if my token would become public.
