Custom folder art for TV Shows not displaying in Library view

For a number of my TV Shows I have covers that I much prefer to TheTVDB’s ones, so I have placed these as ‘folder.jpg’ files within the appropriate folders. When I navigate to my TV Shows folder on my NAS through the Remote section of My Files the images display correctly. However, they fail to displace the automatically fetched images shown in Library view. This problem does not extend to films in Library view, just TV Show folders.


Has anyone managed to resolve this issue?
