New Item Highlight not going away for several categories in Buy/Build

I bought the Bikini Bottom collection and logged into the game to check out the new items. After checking all the new items in buy mode, I noticed that some categories remained yellow, but when I went into them, I didn't find any new items. I tried entering codes to view hidden items and trying to build on empty lots (in case these items are only for public spaces). But no new items appeared in those categories. I don't have many mods and haven't had this problem before. Has anyone else experienced a similar situation?
