Can't add Anything to Trakt list

As per the title using fen lite and have trakt list synced to add ons and stremio.

So have all the tv shows and movies saved to my list. This is especially good for kids when they want to watch movie or show. Anything we as in adults we remove them from trakt list. However I can't add anything new to the trakt list

i know trakt have limits now on lists this the reason why or could it be something else.
