Still getting the default notification sound after TTS

As per title, even though I think set everything correctly, right after the TTS voice I still hear my default notification sound.

(I had to use the microphone instead of internal audio because apparently it refused to record the TTS with internal audio)

Screenshot of the app settings:

I'm not sure if I'm doing something wrong or if it's an intended feature, in which case I would like to ask if it can be disabled, because it would make me think that I have an actual message/notification.
