Because your edit summary was "+Category:Western Animation; +Category:Western Animation of the 2010s; +Category:Western Animation of the 2020s using HotCat The show actually premiered in 2014", but in addition to that you deleted an entire trope and a large number of examples of another trope without explanation.
Misleading edit reasons are worse than no edit reasons at all.
