I’m able to duplicate the problem just by changing the text in the text editor. Which to me indicates a problem with the plugin.
If I put an anchor tag to a media file in the text editor with no other text, the plugin works fine. If I put an anchor tag to a media file in the text editor along with a percent character (%) immediately following the anchor tag, the tag’s href attribute will NOT update when using the “Replace the file, use new file name and update all links” option.
I’ve tested this with both image files (.png, .jpg, etc..) and other file types (.pdf, .xls, etc…) and am getting the same result. Can others please verify that a post containing only an anchor tag will update while a post containing an anchor tag and a percent character will not.
