Not sure if this is an issue with my inbox or the Writing tab, but despite getting notifications like "+1 好 point: your mnemonic for 例", the entry on the Writing page says "好き points: 0". This looks like it's only happening to mnemonics that I've gotten more than one notification about, so I'm guessing either the inbox message should say "-1" instead of "+1", or there's a bug that after the first 好き point the counter on the Writing tab resets to 0.
