What issue are you seeing?

There is an issue with the codex usage panel. Under the General Usage Limits section, it incorrectly shows that you have 100% of your 5-hour usage limit remaining, even though your weekly usage is at 0%. This counter resets every 5 hours; however, it should stay at 0% until your weekly usage resets back to 100%.

What steps can reproduce the bug?

There is an issue with the codex usage panel. Under the General Usage Limits section, it incorrectly shows that you have 100% of your 5-hour usage limit remaining, even though your weekly usage is at 0%. This counter resets every 5 hours; however, it should stay at 0% until your weekly usage resets back to 100%.

1. Exhaust your codex weekly usage, with a remainder of x% > 0.
2. Wait 5 hours for your 5 hour usage limit to reset
3. You should see 100% is now left, despite having 0% on your weekly usage limit.

What is the expected behavior?

You would expect to have the 5 hour usage limit remain at 0% whilst you're weekly limit is finished.
