Hi @MRUIAW , thanks for the PR!

I noticed that your changes are overwriting many of the Japanese translation lines (over 20 spots) that I previously updated.

Could you please revert all changes affecting lines starting with "ja":? >
Those lines are already localized for the current version, and this PR would roll them back to an older or incorrect state. It would be great if you could exclude those specific lines from your PR. Thanks!

@GhostShip1980 hi there! thanks for the reply
I dont really have much time and I dont have my PC right now, but I'll wait until Friday/Saturday and make the revisions then. :>

@MRUIAW Thank you for updating the PR and resolving the conflicts. The Japanese translations are preserved now. Looks good to me!
