Timer calculation issue

I got offline timer that works however the issue is, only 1 vehicle per time gets taken out and given it’s reward. If i buy more than 1 vehicle, after the 24 hours. It takes 1 vehicle out and then proceeds to start the next vehicle's timer n it's stuff.

Currently it works like this, 1 vehicle 24h, reward every 1 hour it gives $4,200 and once the 24h is done it takes the vehicle out, the timer and the reward works even if the player went offline. However, if there’s more than 1 vehicle it waits till that 24h is done then proceeds to starts the next and so on till the vehicles reach 0. And i want it to work like this, each vehicles gives the reward, no waiting for the other vehicle or timer to end or gets taken out.

Here’s their events
Buying the vehicle event


The reward event

The timer n taking taking the vehicle out event

And finally the stop event after the vehicle reaches 0
