So recently, I have managed to perfectly get the inventory item manager to work correctly.
For a while, I have continued to try and get this to work the correct way.
I have used Lifecycles, Repeaters, buttons and triggers but after trying so many times, it finally worked.

you will need
1 Relay
2 Wire repeaters
1 Inventory item manager
How it should look
Make them look like this
Relay
Then wire it all together and you are done
Hopefully this is helpful to you.
