Ink carthridge to be replaced even if not empty

[NL58]

Hi everyone, it seems I'm not the only one that has a HP printer and the printer request I change an ink carthridge before it's empty. Also, if one of the color carthridge is empty, I have to replace all 3 colors otherwise it won't print. And finally, I can't print in a gray / black mode with a color carthridge empty. This printer before some updates use to be able to do all that. Any advise would be appreciated
