fix(patch): Fix occasionally incorrect unit in some tables [2/4] (#329)

## Description

Actually resolves #277. EDIT: or actually not sure if this solves the
same issue. But solves an issue anyway.

Examples:

Incorrect label, saying "M" aka "Mega" (or I guess "Millions" also reads
fine):
<kbd> <img width="832" height="214" alt="Incorrect unit label M denoting
Mega"
src="https://github.com/user-attachments/assets/f8e7419f-994d-4893-a9c3-72954a4c78ce"
/> </kbd>

Correct label, saying "K" aka "Kilo":
<kbd> <img width="822" height="191" alt="Correct unit label K denoting
Kilo"
src="https://github.com/user-attachments/assets/e1953acc-4489-4b24-a7e1-7a84a97e0bb2"
/> </kbd>

To be completely clear, both these images are 100% correct other than
the first image mentioning "M" aka 10^6.

Feel free to review on your own schedule.

## How Has This Been Tested?

Manually in my PRs.

## Minimal checklist:

- [x] I have performed a self-review of my own code 
- [ ] I have added `DocC` code-level documentation for any public
interfaces exported by the package
- [ ] I have added unit and/or integration tests that prove my fix is
effective or that my feature works
