Why is my Mcreator keep deleting some of my elements but keeping the textures and models

I am trying to make a mod, and every time I get anywhere the elements just randomly get deleted. I made config file stuff with a plugin that took forever, and copper plate, and big procedure to go with them, and they got deleted. And just recently I made 4 "Copper Repeaters" and 4 procedures to go with them, and they got deleted again after I turned on my pc. Can someone please help, I am using MCreator 2023.2, I have these plugins: attributes, better crafting recipes, blockstates (Doesn't work with the Mcreator I am using), configuration files, damage procedures, 1.18.2 generator (generator 1.18.2 1.3 2023.2), Marwinekks Procedures Plus, Nerdy's Geckolib Plugin, Procedures Fiesta, SerpZ Mcreator Plugin,  shaders utils, SnalPlugin, WorldRenderer.
