Filtering system issues

The filtering functionality of the watchlist doesn't seem to work. I can select the folders (planning, completed, ect.) just fine, but selecting anything else like the genres or year will just say no anime available or it won't do anything. For example, I just clicked the "mecha" genre as a test, and none of my titles filtered out; food wars was the top (my most recent watch) result lol. Not a huge issue, but it would be nice if it worked as intended, thank you for the lovely site otherwise.
