ラベルが突然つかなくなりました

Hi  一雅安,

What kind of file format you use?

Can you rate or label your images after purge cache (select the images, right-click and then choose 'Purge Cache for Selection')?

Can you rate or label your images if you copy the images to your desktop?

If the issue still persists,

Please reset Bridge preferences as mentioned in this article Troubleshoot Adobe Bridge for freezes and performance issues

Let us know how it goes,

Thanks,

Akash
