Hi TaeHo01.
This sounds similar to this other thread.
If you can provide some additional information it will help us investigate.
- What browser and operating system are you using?
- Are you able to open the developer console and check for any errors in the console?
- What is the asset id you are having problems with?
- What location are you trying to set? Are you able to post a screenshot or video of the UI before pressing save?
