I Broke my Docker Container With a Spelling Error

[ZeHolyQofPower]

Okay, I know this is really stupid, but I can't figure out how to fix it.
When I did Homework2, in my Dockerfile I misspelled the name of my repo and no one noticed. When spinning up my container to test my code, I found this error and decided to correct it.
ARG REPO_NAME="csce274_attemp_ii" vs.
ARG REPO_NAME="csce274_attempt_ii"
Now when I start my container, it seemingly remembers both the spelling error and the new correction. It duplicates all the code in the Catkin workspace for each, it consistently starts me in the old directory, and only the new directory is in sync with my code and github repo.
Example of starting up:

Well, if I delete the old directory while inside the container, it doesn't save because, duh, it's in the container.
I have searched and searched using a combo of grep, cat, and tree and there is no mention of "attemp_" without the 't' anywhere in my repo so I have no idea how Docker is remembering this old directory?

Also for the record, I really need to delete this old directory and can't just ignore it. It has caused me so much confusion and anger until I finally figured out what was really going on.
