Most of the titles on this commit already are tagged as mecha on MAL.
Remember that MALgraph automatically counts titles towards specific achievements, if their genre matches the genre ID. Take a look at the file, and you'll find this:
"type": "genre-titles",
"genre": 18,
It means that titles from genre 18 (mecha ID on MAL) are automatically counted and there's no need to explicitly specify them.
If you feel there are some titles that need to be added, and they aren't tagged as mecha on MAL, please fix the aforementioned issue by removing redundant entries.
