As far as I understand these things (so until GaJ corrects me), I think it is reasonable to assume that these reusable “tags” are still pulled from Pootle and the auto translation works only for the descriptions the author of the joseki provides. So you should be able to improve upon the aforementioned and screenshotted tags.
I see you made some changes into the translations recently, so if you are wondering why they did not show up yet, it is because these are not processed in real time it usually takes a day or two for them to process.
