I modified the ammunition to 16, but it always shows 40. I've already reloaded it, and I don't know what's causing this.

Which stack plugin are you using?

Personal MLRS 1.0.1

I was thinking about the item stack plugin.

No need to open a new ticket for every answer!!!!

Sorry, author. This is my first time using this and I don't quite understand. I have to rely on translation. I'm truly sorry.

I really like your plugin and I'm planning to purchase it, but I have to solve this problem first. Thank you.

Try disabling the stack plugin you are using. And then you should be fine.
