Open Design会在每一次问答重复的发送之前的老图片？Open Design send the old pictures before each repeated Q&A session?

[Ashbackslide]

在某次问答附上PNG附件后，后续每次问答AI都会重新读取一次这个图片，这让AI变得很困惑又愚蠢，必须要关闭opendesign再打开才能清除，如何才能解决这个问题？我已经尝试了在项目文件夹里删除图像并且在右侧设计栏关闭相应标签，并没有起到效果。
After attaching a PNG file to a question-and-answer session, the AI re-reads this image every time for subsequent sessions, which makes the AI very confused and stupid. I have to close and reopen opendesign to clear it. How can I solve this problem? I have tried deleting the image in the project folder and closing the corresponding tab in the right design bar, but it didn't work。
