I forgot which one it was but all I know is that it was a small hose but they said they checked it again but I’ll be going this Saturday and hopefully is nothing major

I had a leak repaired, and the tank needed filling for a couple of weeks, until all of the air voids in the coolant in the engine and heater had filled up. The it stopped going down.
It takes several hot-cold cycles to do this. I don’t use the car every day, so it took a couple of weeks to stabilize.
If the radiator cap is leaking, you will often have no evidence of this, because it comes out only when the engine is hot, and it goes out the overflow tube.
