Typing and Erasing Words on Agenda Clunky

I am typing within a note, but I notice that it will have a significant slow down when I go to erase words. Typically, I use the command shortcut to erase a whole word and begin typing again.

I am not sure if anyone else is experiencing something like this. I read a few people in the support community having similar issues a couple of years back, but it had to do with scrolling not typing. I am using a MacBook Pro 15 2018 on macOS Catalina. My Agenda app is running version 9.1.3.

Please help.

Is this in all notes or only in some, how big are your notes on average, or does it have a lot of images, tags, or attachments by any chance?
