Regarding Images Saved in an Environment Affected by This Issue

When you open the image editing screen and save again using the latest fixed version of the app (Ver.7.4.2), the text will reappear.
As a result, text you did not intend to include may appear on screen.

Since it is difficult to identify which images are affected, if unwanted text appears during re-editing, please manually delete it and save again.
