Only Download Subtitles (using A4kSubtitles) When Missing?



I have installed a4kSubtitles on my WIN 7 PC running Kodi 18.9. I have set a4kSubtitles to “Auto Search”. It then only searches for subtitles if they are missing. This is how I want it to work.

On another PC, I have WIN 10 and Kodi 19.5 with a4kSubtitles also set to “Auto Search”. However, on this PC Kodi searches for subtitles even if they already exist. Is there some Kodi setting that I need to change on my WIN 10 PC so that it only searches for subtitles when missing?
