I would like to know if you have received an error if so, we can perform a cache troubleshooting steps or guide you on how to edit the item in your inventory. Additional information would be helpful. As of now, we are going to check if you have experienced cache issues on your browser.
First, access the incognito browser to check if the process is smooth while changing your inventory item. Here are the keyboard shortcuts for the supported browsers:
Google Chrome: Ctrl + Shift + N
Internet Explorer & Mozilla Firefox: Ctrl + Shift + P
Safari: Command + Option + P
If you're able to edit the inventory item using a private or incognito window, then we'll need to clear your regular browser cache. However, if the issue persists, try using a different browser. This way, we can roll out the possibility of a browser integrated issue.
