@LavenderPawprints @lynnskyi @luv4music1231 Yep, this is definitely an issue with multiple apps unfortunately.
Take Ivory, for example, as I don't use the others you mentioned. Ivory has their own filter rules which are arguably better than Mastodon's own filters in certain ways. Ivory lets you specifically mute hashtags for example. Mastodon originally only lets you mute keywords, you have to add the hashtag yourself. They also have a "potential spam" filter that they've added themselves.
So, that being said, I'm guessing other apps do something similar and those filters don't get updated to the site for those reasons.
That's just a slight guess on what the issue is, because I'm not a dev, I just see what I see and make very decent assumptions on why they're like that.🤷♂️
