Very minor bug in JQ race

Hello, I'm a JQ pervert who live and die for JQ, keeps track of JQ races along with IGNs of recent winners.

Disclaimer
No offence as this post is not meant to pick on my fellow JQ loving players, nor to get back my lost medal.
Screenshots are there to prove my point in reporting a very minor error in JQ race.
As this contains a lot of TMI, do read this with empty mind. LGI !!

Intro
This happened on 12/Nov/2021 when automated JQ race was hosted at 07:00 PST which was overlapped with GM hosted JQ race at 07:15 PST.

Body
Winners for 07:00 PST, Tomb JQ race was as follows:
1) EbiGuy
2) Eggbi
3) Fishyfishy

The bug was found when late-comer for former JQ race taking the latter JQ race medal.

Hence, winner for 07:15 PST GM hosted Mt.Saga(Hard) race was as follows:
1) Raephyr
2) Orbea
3) EbiGuy

As megaphone might have been faulty, I checked my before and after JQ race medals from https://maplesaga.com/jq-rankings
Since the ranking list do not update real-time, I was able to further cross-check the errors.

The before and after for the two consecutive JQs are shown below:
Before:

After:

This shows increase of 1 gold and 1 bronze medal, in which the megaphone was not faulty.

Summary
1st/2nd/3rd medal for JQ race seems to get its reset when another JQ race is hosted regardless of previous ongoing JQ race.

It would be ideal to have a tag (any random alpha-numeric sequence) in each JQ race.
Pros: This may allow medals to be given out according to the relative JQ tag in case a duplicated race was hosted.
Cons: Inefficient if considering the complexity of code along with frequency of duplicated races.

Big thanks to everyone who read this :3
