Bug Collecting Bug

I have made a post already in help with MCreator software about this but I believe it needs to be a bug post.

I currently have a feature where you can collect bugs in jars. This includes two modded entities and the already existing bee.

The procedure works fine in creative, or in survival if I only have one jar. However, if I have more than one jar in my survival inventory, it for some reason creates four in my inventory and the last two of them are 'ghost items' that disappear if they're clicked or used.

Here's a link to the procedure I have in place, it does continue but it is the same thing repeated over and over just for different mobs:

Here's a link to a video demonstrating the bug:
