Non-Stackable Items Stacking

I am having things like guns stack in crates.

Did you configure a custom stack size for weapons or are you using a stack size multiplier?

I have your stacking disabled. I have another stack plugin, but it doesn't allow stacking of weapons.

Then it is almost certainly caused by stacking plugin that you are using.

Keep in mind that this plugin is not intended to be used in combination with other stacking plugins.
