Title and caption (+ author) are not displayed in right side-view "captions/tags" of the image editor. Similarly, when you write a title and a caption in the image editor, once you apply, they are saved but disappear.
Not reproducible here. I tried with a lots of photo without to be able to see this dysfunction. Which kind of image type your try to tag ? Did you write metadata to image ? If yes, which settings did you use ? Also, turn on debug spaces and run digiKam from a console while you reproduce the problem. See here for details : https://www.digikam.org/contrib Gilles Caulier
Ok, I understood the problem: it was a fresh installation and the language metadata was not defined neither x-default nor a specific language. Once I selected x-default or a language, it works well for the image and the following. In digikamrc : [ImageViewer Settings] [Right Sidebar] [Captions Tags Properties Tab] ImageDescEditTab CaptionsLang = ImageDescEditTab TitleLang = were empty, like that. So to reproduce the problem, you must delete the values and restart digikam. Note: In a fresh installation, ImageDescEditTab CaptionsLang TitleLang and is set to x-default for [Digikam Right Sidebar] but is empty for [ImageViewer Settings] and [LightTable Settings] [Left Sidebar] + [Right Sidebar].
