Incorrect mask generation

**Describe the bug**
Incorrect mask generation. Clicking Submit or Update generates a row of tiny masks on the far right edge of the image.So much so that the generated dataset is inaccurate in the bounding box generated based on the mask, I have the latest version and use chrome for my browser, I solved the problem briefly after updating to the latest version, but the problem reappeared half a day later.
