Japanese commas mess up LingQs

The text after the comma does not appear in the LingQ itself, yet shows up in yellow in the lesson.

Russian commas seem to work fine. How about in other languages?

The system seems to struggle a bit with Japanese. It’s so easy to create them in French, but it’s manual labour in Japanese. I edit them by hand and add in an example from ALC.

Are there any other commonly-used Japanese punctuation marks that are likely to make LingQ go pear-shaped?
