Hello, I'm trying to add a new item using Blockbench. I've read the WIKI and checked YouTube, but to create an item with the body, I found out that I need to download the cceditor.js plugin from Blockbench and create a separate 'self' section to adjust the position. In the process of executing it, I wanted to further adjust the Y-axis direction by pressing "auto fix selfmodel." However, when I press it, I get the error message "ERROR! Please set size to the same value for each scale property of the body cosmetic preview! Do not use different values." I haven't touched anything else, only pressed "auto fix selfmodel." Do you know why this error is occurring? I would appreciate it if you could provide some guidance!
