Home assistant playing all old text to speech files

Hello guys,

HA is running the latest stable version. Currently I am running a room sensor and got it working with text alerts on phone. Now since I wanted to have key messages played out, eg: kids leaving school reaching home, delayed reaching home etc, I started playing around with text to speech by using call service action.

The issue I am facing that including the testing to tts done via developer tools, all the conversions are being played together in each trigger. Any idea how to clear old file caches? Thanks again.
