I get input bar at the bottom of the app when I type in

Hi,

I am a beginner who just started to use Premiere Pro and I usually make titles in Korean.

I don't know if this may be a language related problem but, whenever I type in Korean, I get this input bar at the bottom of the app.

The greyish square input bar is what I'm talking about. I don't get this problem when I type in English.

Does anyone know how to remove this? I'd be really helpful to know because it's been bugging me so much. Thanks !
