Could you run the following script and see which logs are missing?

https://gist.github.com/bas-vk/299f4a686b66a22cf87302c561ee5866

The script assumes geth is running on http://localhost:8545 and parity on http://localhost:8546 and is synced >= 275836 (on ropsten).

The dumped logs contain a tx hash. Could you see if you could fetch the receipt for these transactions and see if the receipt does contain these missing logs?
