can not change the word "mileage"/"miles"

Hey,

Nice catch! This is indeed a bug on our side, we did make the backend label translatable but didn’t make the abbreviation that is used on the frontend translatable.

We fixed this in the master branch of our repository (https://github.com/barrykooij/wp-car-manager/commit/99d9b297c301afe1d2463908ef9e3fec281e96e1) and this fix will be included in the next release.

Thanks for reporting this and thanks for using WP Car Manager.

Barry
