Sound bug in resupply lockers

When testing my map on a dedicated server, I found an interesting sound bug with the resupply lockers in my map.

If a player is on the red team and near a resupply locker, they can hear it's sound coming from it when a player on the blue team touches one of their resupply lockers. The same goes for players on the blue team when a red player touches one their resupply lockers. However, if a player on the same team touches a resupply locker, the sound will only come from that locker and none other.

I checked my locker props and triggers for them. All checks out fine. Example: Trigger func_regenerate is set for prop_locker_red_7 and is set for the "Red" team. Same checks out for all the other resupply lockers as well.

Everything checks out fine with iterlopers as well.

I should also mention that all resupply lockers are from the ABS Ultimate Map Pack rather than self created.

I put in 2 more resupply lockers but manually made them this time. One for red and one for blue but, they only produce the same results.

Seems it has something to do with the triggers as this time I used a different locker prop and even gave them more simple name like "red_locker_1". Yet the sound still comes from the other team's resupply lockers.

I'm starting to run out of ideas.

Yup, all have different names. I went as far as naming the triggers with different names and still got the same results. Figured hey, what could it hurt at this point lol.
