Hello Tyree,
Jupyter Notebook/Lab is a browser application (talking to a kernel). From what you described, it looks like something triggered some kind of auto-correction. From your example, clearly the "ur" in the word "Our" was understood as "You're" abbreviated and got auto-corrected. This is not a native Jupyter feature. It might be a browser plugin or some custom Jupyter extension.
Are you using a Jupyter installed from an official source? If so you can raise an issue in the corresponding repo as suggested.
Thanks,
Gabe
