New smart collections don't work properly in Lightroom 4
All of my old smart collections are fine and have the correct number of photos, but new smart collections contain way too many images... thousands when there should only be hundreds at most. For example: I'm trying to create a smart collection of all of the images with 3+ stars from February 2018, but the smart collection pulls all of the images with 3+ starts from February for every single year. I've been creating smart collections the same way for years, and new smart collections are made exactly like previous working collections. I don't understand why I can't make any new collections. It seems to be an issue with my 2018 collection set as creating new smart collections in my 2017 collection set work fine. I've deleted the 2018 collection set and remade it and the problem persists. I've optimized my catalog and restarted my computer and it did nothing to fix the issue.
